Customer Reviews Stanley 18 oz Master Unbreakable Packable Mug

I use this to protect my home

Love it! Stays cold forever! Easy to carry and it's a great size!

Nice finishing. Good material.. But heavy. Use for travel No leaking.

It rocks! As in rock solid. Easy to clean this legendary rock solid piece of equipment. Buy it - no disappointment to be found. Does what it says - it really works.

Really love this tumbler. I toss it in my bag on the way to the gym and have hot coffee waiting for after.

Very nice, keeps my coffee very hot all day, holds enough for a coffee break and lunch too.

Hands down, Stanley products are the best there is. I have purchased all of the pretty, newfangled brands - yeti, hydro flask and others, and they do not keep a hot drink hot for the time that a Stanley does. Most recently, I was hiking in the Adirondacks, on a cool and rainy spring day, and my tea was almost too hot to sip even after nine hours! You must preheat the mug, as instructed, and put in hot liquids, but once that is done, be assured it will be hot - AND will not spill even after bouncing around in a backpack. Thank you!! This is my 5th Stanley product, and all have been fantastic.

Got this after way too many "leak proof" mugs had made cleaning singed coffee off my motorcycle's exhaust pipe an annoying daily hobby. So far, this is the perfect thermos to throw in my saddle bags before a ride.

Love it! I take hot bone broth with me to work! This is the perfect vessel in the perfect carrying size!

Bomb proof... Kept my tea hot for hours... Even at the top of mt. Washington in NH

Love this Master Series. Purchased the thermos earlier in the year. Keeps my coffee hot throughout the day without fail. I like this smaller version "thermos tumbler"with its simple twist on lid. Used it for my hot coffee this past week and no leaks due to its simple twist on top and seal. So happy I purchased this. Great as a gift for our other coffee lovers and cocoa connoisseurs. Good Job Master Stanley! Good Job!

The simple design wi the rugged feel is awesome. I take it everywhere . It fits in my car cup holder with coffee . And at home with a cold beer. The lid is simple on and off so I can just grab it and go. You can also snap on a back pack if you need to.

I make 2 travel mugs of coffee with me to work every morning. One for drinking from and this one to keep my refill hot til I'm ready for it. Even if I wait til mid afternoon to have my refill, it's still piping hot. Sure, I could just make a fresh pot of coffee at work, but the coffee I make at home is so much better. I know I could fill this with boiling water before leaving for a hike in the morning and it would be hot for my dehydrated meal at lunch or even dinner. Thanks Stanley!

This was well worth the money and is the perfect mug for soup later in the day. may not be the best for long backpacks as it fairly heavy but it is durable.

The mug is great, I love it, I was extremely happy with my purchase until I took the mug for a drive and tried to drink from it while driving. If you think you will use the mug on this situation, get another model.

If you like to leak room temperature coffee all over the place, this mug is not for you! It utilizes some sort of Alien Technology and/or Demonic Magic to keep coffee hot for hours (days/weeks/months??). You'll need to leave the lid off for a long time just for your coffee to cool enough to drink. The lid won't leak, even if you throw it off a speeding train or use it as a bat during an impromptu baseball game. I'm no thermos expert, but I believe the thermos is constructed of a material made of pure lava and rocks from the sun's orbit. Overall, I would recommend this thermos.

This product has the best design and performance. You just need to grab and touch it to find out how much it is valuable.

This mug has become my absolute favorite . This mug is rugged and strong. It keeps hot tea / coffee hot and it keeps ice water cold ... it fits in my cup holders . This master line is a 10

I purchased this mug at REI about a month ago, and it has exceeded every expectation that I had for it. It'll keep my coffee hot for well over 12 hours and is extremely heavy duty. I use this daily and absolutely love it. Keep the Master Series products coming! Maybe a lowball tumbler soon? I was considering the Yeti 18oz bottle, and I'm glad I chose the Stanley. This product is superior to the Yeti by a mile.

I bought this a few weeks ago expecting it to be like other Stanley products. I have used it everyday and it is amazing. It will keep my coffee hot 24 hours. You can tell it is better made as soon as you pick it up. It is heavy duty. You will not be disappointed. Marine approved.

Mine actually does leak after I dropped it once from 3feet.

The mug does A great job of keeping hot things hot and cold things cold. It's a manageable size and carries an adequate amount of water for short outings and trips. A great addition to any gear set.

I now have 2 of these, they seem to keep the cold much better than the hot. I have an old 12 oz Thermos Bottle than retains the heat much longer that this bottle. the Thermos bottle is still drinkable the next morning where as this is cool to the touch, even in the hot summer weather. I pretty much just use these to pack some large ice cubes for cocktails out on the trail.

Really disappointed with this product and particularly the lifetime warranty. My wife bought me the master series thermal mug here in the UK but after a year or two it no longer kept the contents as hot. I sent it back under the lifetime warranty but they company they use to sort out warranty claims wouldn't or couldn't replace it and instead sent me the classic trigger mug which as anyone who has been able to compare the two products will know, is a completely different product and worth half the value whilst being no where near the same quality. I've tried asking them to replace it with a Master Series product but as far as they are concerned it is case closed.
