This is the one!
After buying many thermal cups and returning them because they didnât stay hot long enough for me to finish drinking my coffee in about a half-hour, Iâve finally found the perfect thermal cup.The difference is the vacuum seal. Well made and sturdy; tight seal and does not leak; stays very hot for about an hour and warm for a few hours; fits nicely under my small Keurig without having to remove the bottom piece; dishwasher safe; easy to remove the sturdy lid; easy open and close sipping hole. This cup is not flimsy.Some have commented that itâs difficult to remove the lid, but if you open the sipping hole, the lid unscrews on and off easily by releasing the vacuum seal.Another feature that sets it apart is that I can brew a 12-oz cup of coffee without the water overflowing, with room to spare.I have only positive things to say about this cup. Itâs perfect and far superior to the others Iâve tried, including expensive popular name-brands.

A well made made function design.
The thermal quality is as good as any out there. I especially like the simplicity of the design… fits well in the hand without an annoying handle getting in the way as you go about the day. The slide open feature is smartly designed… does not stick OUT or UP when opened(unlike other poor designs out there).

probably better than the coffee cup you already own
bought this cup because i needed something to hold my hot coffee in when i go to school and paper cups just are messy and a disgrace if im honest. great thing about this cup is that it keeps my hot coffee hot for a very long time. by the time i finish it it is still warm but like not regular warm like more on the hot side of warm like if there was a spectrum it would be between the middle (which is warm) and the right (which is hot) and usually i finish it about an hour and a half after putting the hot coffee in. its so good that my dad even claims that it hold his coffee hot for around FOUR HOURS which is insane obviously. also it never leaks like once i dropped it in the hallway and it was so loud and embarrassing and this boy behind me picked it up and afterwards i had to walk in front of him for the next minute or so. i wanted to crawl into a ball and disintegrate, but guess what? it didnt even leak one drop. wow. the only downside which would be why i gave it four stars instead of five is that it is squeaky as hell. now, i know this is a stupid complaint but when it is 7am in the morning the last thing i want to hear while i twist the top on is a squeaky sound. like if you drag your finger on glass i HATE it. but, because this coffee cup has made so many of my terrible early mornings not that terrible, i will overlook this small inconvenience. i love you guardian collection by thermos 12 ounce stainless steel travel tumbler in blue and i hope that we can continue to share our mornings together for a very long time.

Leaks. Bad design.
I needed a leakproof container. This leaked all over and has a stupid design. You have to remove the lid to open it while it is covered with your drink, then put it back on to drink. I returned it.

Best travel mug yet!!
This was my second purchase of this mug. I bought it for a friend for Christmas since I loved mine so much. This mug comes apart completely to clean. The two plastic rings come off, the inside of the lid comes off. The easiest travel mug to clean ever. It keeps my coffee nice and hot for hours with no need to temper the mug first, even though that might help. Leak proof *as long as you remember to put it all back together* twice Iâve grabbed my mug and not make sure it was reassembled correctly and ended up with hot coffee all over me. I check it now and donât assume. Great product – only complaint is – I wish it was larger. But that a personal coffee issue.

Colors have different lid designs
I ordered one each of the Slate and Matcha Green colors. I noticed that the lids have significantly different designs. I haven’t yet compared their efficacy, but it would not surprise me if one of them works much better than the other.I did have an issue with the Match Green one leaking a little while on a hike, but my drink was still lukewarm after about 2 hours of being out in 35° snowy weather.

Es el segundo termo de estos que le regalo a mi papá. Le gusta mucho porque cabe en la cafetera Keurig, cabe en el portavasos del carro, es resistente a golpes, no se tira y mantiene el café caliente por bastante tiempo.
