Customer Reviews Stanley 20 oz/.59 L The IceFlow Flip Straw Tumbler

Thanks to the Stellar Review Panel for the opportunity to review this. I've only had it for a few days but so far it definitely does the job of keeping my drink cold for a long time. I'm not one to slowly sip the same drink all day but it kept my water perfectly cold for at least 4 hours while I was working. The handle on top is convenient for carrying to the car when I have 15 other things in my hands. That said, it does seem a little heavy for the volume it holds. I like the straw and it's easy to detach and clean. The flip up straw is a little stiff to flip open and sometimes I have to use both hands to get it open, so I really just mostly keep it open and it doesn't seem like it will spill easily. It also fits pretty well in the bottle holder on my Peloton so I can keep my water a lot colder through my rides versus the thinner plastic bottles that I used to use. The narrower bottom seems like it will fit in most cupholders well, it fits my car perfectly. The one thing I really haven't tested is how easily it dents. I drop my metal tumblers all the time and all my others have at least one dent so it would be interesting to see how many falls it takes to dent this one. It sure seems more sturdy and solid than my others. All in all, I really like it, except for the color. But I didn't get to choose that.

I received this water bottle to try as part of the Stellar Testing panel. The water bottle itself is made very well and the insulation is great. It kept my ice water cold icy for at least 4 hours. My only issue with this cup was the straw. The flip out spout had to be at just the right angle to work properly, otherwise the suction was not strong. I attempted to adjust the straw multiple times and it did not seem to help. Once I figured it out though, I loved it! The handle is helpful when I'm carrying it around and chasing after my children. I would recommend this water bottle to anyone who likes to keep their drinks extra cold for long periods of time.

I received this tumbler as part of the Stellar Product Testing Panel. The durable structure of this tumbler makes it ideal for life with a lot of kids. The dual-wall design kept my drink cold and with ice for more than twelve hours. It fits in my cup holder in the car, and it is dishwasher safe which I love. The design is not fully leak-proof if it isn't upright, unfortunately. Just remember not to throw it carelessly in your bag. My straw also seems a little bubbly, as if it's letting air in somewhere, though I haven't been able to find out where. My favorite feature of the water bottle is the big handle it has, which makes it easy to carry with one finger, or to clip on to a bag or the stroller. Overall, I'm really pleased with this product!

I received this 20 oz tumbler from the Stellar Panel in exchange for my honest review, and when it arrived I was immediately pleased with the finish. It is a water bottle that definitely feels nice when holding it my hand to take a drink. The overall shape of the tumbler makes it fit really nicely into every cup holder I have used so far. I have taken this water bottle on walks with our stroller and in car rides and it always feels secure in the cup holder and doesn't seem like it will fall out. I also love that I can have the convenience of drinking from a straw without having to give up on the idea of having a water bottle does doesn't leak. I do wish however that the straw on the inside of the bottle was not plastic but rather stainless steal to make the life of it last longer and to make it easier to clean. It it always nice to know that you are helping even more stay out of the plastic realm. Other than that, this bottle has been perfect. It keeps my water ice cold for at least 4 hours which is definitely more time than it takes me to drink 20 oz and ready for a refill. As mentioned above it is totally leak proof in my experience so far, and it is really nice that this bottle is dishwasher safe. I have always been worried about compromising the vacuum insulation of my water bottles in the dishwasher so to know that this one is so each to wash having that dishwasher option makes it totally worth the purchase.

Thanks to the Stellar Product Testing Panel, I got to try out the Iceflow Flip Straw Tumbler. The tumbler is heavy duty, seems very well built and durable, and didn't leak! This is very important for my family with two active littles under five years old. Cups get dropped time and time again and most end up leaking; however, this one has held strong and hasn't even gotten a mark or scratch from several falls! The lid and straw are a little hard for my five year old to open, but I'd rather have that than leaking drinks! My water stayed cold and the ice frozen all day through several refills. I'm very pleased with this tumbler and definitely recommend it for active families that need dependable water bottles that will hold up to life.

The design and style definitely fit the intended use. It is a great cup for the active and outdoorsy crowd (myself and family included). I am a Navy-veteran, mom of 2 young boys and a lab fur-baby, wife to an Army husband and 8 months pregnant in the middle of summer in Florida. This tumbler has been a life saver. I have used it everyday and it has kept me hydrated with ice-cold water all day. Down to the last drop too (I can get almost all of my water out with the straw). I even have it next to my bedside so when I wake up I can have cold water at the ready. That's roughly 8 hours just right there. It is dishwasher safe so just a quick round in the washer and I'm back to the grind. The tumbler is a little heavier than usual but the handle makes up for the slight inconvenience. It's pretty solid and sturdy and has taken some beatings from my family and I already. The handle helps me get my kids out of the truck without having to finagle one handed or set it on the ground. One of my favorite parts is that it really is spill proof. I have thrown it in my purse, diaper bag and beach bag and not a drop has leaked. I only had one issue and its the reason I had to give it only 4 stars. I had a difficult time with the straw. I would get a lot of air and minimal water as if there was a hole in the straw. I would take the lid off and push the straw in and it would work great for a little but then sometimes back to mainly air. I then pushed down on the rubber piece by the vent and that would work other times. It has been a bit annoying trying to figure it out but now that either one of those does the trick for the most part I can live with it. The pros definitely out way that one con. It hurt me to take that star away but momma needs her water ASAP with no fiddling. Thank you to the Stellar Product Testing Panel, I was sent this tumbler in Aloe for my honest review. I am planning on buying another one in Guava so I think its worth the fuss. Enjoy!

The Iceflow Flip Straw Tumbler 20 oz did not disappoint in keeping my water iced cold for more than 8 hours. It's not bulky or heavy and it fit perfectly in the car cup holder. The handle makes it easy to carry on hikes, sports activities or anything you can imagine. I encountered difficulty drinking from it due to an unsteady flow. Air seemed to get trapped in the straw. I rigorously shook the tumbler to test of it leaked. It did leak with the flip straw open and only one or two drops dripped while it was closed. That is something to keep in mind while placing in a bag. I am so glad I was given this water bottle to try as part of the Stellar Product Testing Panel.

Thanks to the Stellar Product Testing Panel for providing this water bottle. I constantly carry a water bottle around with me daily, and this one did not disappoint; I have found myself still using it on a daily rotation. Does it do what they say it will do? Yes! I filled it up to the brim with ice and water before heading out for a seven hour day at the lake with boating and activities, and when we were done I was out of water, but the ice was still in my cup. I actually forgot it at one point sitting in the sun on the dock and came back to cold water. I was very impressed with this aspect of this bottle. Design: This water bottle is extremely durable which is important to me since I have two young kids who drop things all the time. The carry handle is easy to use but a little bulky. However, it was also easy to clip onto my stroller clip. I love that it fits into my car cupholders and is easy to hold. I am taking off one star because I prefer for there to be a button or some kind of hands-free way of making the straw pop out. Ease of Use: Oftentimes I have trouble unscrewing the lids off of bottles, but I didn't have any problems with this one. The carry handle made it especially easy to take the lid off.I could tell it was made of high quality materials. The straw is easy to use and doesn't "activate" to drink out of until its fully popped open which is nice. I like that you don't have to bite the straw or suck hard on the straw to get your drink to come out which is the case in some leakproof cups. It is not completely leakproof, but I haven't found any bottle that is completely leakproof when dropped down stairs accidentally by a toddler. When it was dropped from the top of the stairs all the way down to a tile floor covered by a thin rug it didn't scratch it or affect the functionality of it in any way so it is extremely durable. My three year old and one year old are able to drink out of it and carry it around unassisted. I also love that it is dishwasher safe because any way I can save time is always helpful to me which also makes the cleaning process much easier. I do wish it came with a small cleaner to clean the inside of the straw because I could see it getting moldy (some of my other bottles have; this one hasn't thus far), but I was able to use a bottle brush cleaner fairly effectively.

Since receiving The Iceflow Flip Straw Tumbler 20 oz from the Stellar Panel to try, I have been using it daily. I love having a water bottle that can keep up! It not only keeps my water really cold all day but is easy to use as well, even one handed! I will note that it is a very heavy water bottle so it may not be the best choice if weight is a factor but for keeping drinks cold, it is great! It is also very rugged looking, not as sleek as many other options on the market, this looks much more like a heavy duty thermos.

I would consider myself a water bottle connoisseur--I have a huge kitchen drawer full--and this Stanley water bottle is a great addition to the collection. My favorite feature is the durable stainless steel. While I still use bpa-free plastic sometimes, I definitely prefer the stainless option. It's a great size (not too big or too small) and it's nice that the bottom is more narrow than the top, so it fits in the cup holder in my car. Speaking of my car, I left the water bottle full of ice and water in my car on a scorching hot day and when I came back a couple hours later the water was still cold and full of ice. So, the insulation really works! I haven't tested it with a hot beverage yet, but it seems like it will work just as well. The bright green color is great and I also love that it's dishwasher safe. The only drawback is the straw. No matter how hard I try, I can't seem to get proper suction and it gurgles. Luckily it's just as easy to use the bottle without the straw, so it's not a big deal. Thanks to the Stellar panel for sending me this water bottle to test out.

The The Iceflow Flip Straw Tumbler 20oz is a great option for a durable, easy to clean, stainless steal water bottle. I love that it fits in cup holders, has an easy carry handle, is dishwasher safe and has a large opening which makes adding ice easy. It's been hot here lately, around 100 degrees and humid, and the ice does melt quickly but the water itself stays cool enough to drink comfortably. The cup doesn't sweat which is a plus. I've been drinking all the water before too many hours have passed, so I tried leaving cold water in it overnight and leaving it out, which resulted in cool water in the morning. I found that the straw bubbles when the spout is flipped all the way open for some reason. Slightly closed it works best! Also, it's a bit hard to open the flip spout because it snaps closed to prevent leaks. If you have arthritis or something this might be a real problem. For some reason mine has leaked twice in my car when not in the cup holders. The first time I thought maybe I didn't have the lid twisted on right, but the second time I'm not sure what happened since it was tight and the spout was snapped. Overall I have been enjoying this water bottle and will continue to use it this summer. Thanks to the Stellar Product Testing Panel for providing me withthis water bottle.

It is really nice. Feels sturdy, seals well, keeps drinks cold. The only improvement I would make is I don't love the plastic feel of the straw top. It would be nice if it was softer, maybe silicone? Not sure how you do that and keep the seal part the same, but it would be an improvement.

It's fine, but I bought it for my 5 year old to take to school, but the top was really hard to flip open, even for me. I ended up having to trade with a lid from my water bottle so that he'd have a lid that he could actually open on his own.

Upon receiving the thermos I was immediately impressed. The shape, design, color and weight of this thermos exudes quality and sturdiness. This is probably one of the most well put together "Solid" thermos I have ever seen. I love the use of hex head screws, exposed metal, and "STANLEY" logo, which gives this thermos a very "Industrial" feel. I stored both hot and cold items in this thermos for a considerable duration and the thermos performed equally in each instance. The ice in my beverage stayed solid for the entirety of the period of consumption, approximately five hours. This is impressive because I was deep sea fishing in Florida at the time. Unfortunately, my thermos had a defect. The flip up straw component did not seal properly underneath when in the upright position. I checked to ensure that the feeder straw inside the thermos was properly connected after cleaning and it was. Although the top of this thermos is sold and definitely durable, it was not able to create a proper seal and therefore any attempt to drink from it created aeration and did not allow for proper fluid flow. I attempted to adjust the angle of the flip-straw in order to amend this issue but sadly, to no avail. The result was the same for both heated and cooled beverages. I must say I was truly disappointed because I was so impressed with this thermos and my perceived quality. I do hope that my experience was the exception.

Hi Stanley I ordered one of your 20 ounce cups and when I received it the logo was incomplete

Not leak proof! It's average, at best. Maybe the others are better but this is definitely not leak proof. And ice doesn't last long in it.

I love Stanley cups, have some for me and my kids, but one of the ones I ordered makes some rattling noise It's like a small rock or bead or something is in between the stainless steel As it's so annoying! I ordered two and only one of them makes the sound

I love the stanley brand so I was excited to buy these for my kids. They are the perfect size and keep the water cold but my only complaint is that they leak! It says leak proof but we have more than one and they all leak if not standing upright. Wish this was not the case or I would def buy more.

I really do like this cup it does what it does but I feel like the cup could keep the ice colder for longer while having this cup for a couple of months I feel like the ice isn't staying cold, yes I know that it only stays cold for 35 hours but when I fill it up with ice and water to go somewhere it seems like it melts in 2-3 hours and if I fill it up at night and still has ice it seems it will be melted in the morning even though it should stay iced all night and at least an hour or two in the morning.

Overall I love this cup! I bought them for my kids but the flip up mouthpiece is too stiff for them to open on their own. The handle is super convenient to carry 3 at a time though when heading out for the day, and the size is generous. My kids love that the ice they put in it in the morning is still there hours later.

Love this cup but out of the 3 I purchased one of them did not have a hole in the straw. Specifically this green one. Wrote to customer service and didn't hear back. Just wanted a new straw sent. I did cut it myself but it makes a very loud noise now anytime a sip is taken.

The cup is great, however, I was expecting it to have a base like the 20 oz tumblers and it doesn't. The bottom of it is bigger and doesn't fit in cup holders as well as my regular 20 oz. It's good but I wish that the bottom size was consistent with the 20 Oz tumblers.

The cup is great but I bought it for my child and the lip to flip up is very stiff and he cannot open it up on his own. I thought it would loosen up some after use but it is still very stiff. Great cup for older children probably 10 and up.

Love the cup however the small metal circle on the bottom of the cup has fallen off.

Great quality. Everything about is high quality and stylish. EXCEPT, the drinking spot is very difficult for my toddler to open by herself.
