Hot and leak proof
Review Image by Joyce
I love this thermos and used it when I went on my trips. It kept my coffee hot for close to 8 hours and it did not leak at all. It is an excellent coffee mug I've had others but this is my very favorite! The top turns to open to drink from the lid and close whether you are left or right handed.

Coffee
I love these cups. They are awesome. They keep coffee hot just like a thermos. The lid is definitely leak proof, no wetness at all will leak. I have bought 3, unfortunately my mind ain’t what it used to be and I left the cup twice on my truck and it fell off and was ran over… twice! At $30+ a pop I can’t afford to keep buying lol but very much worth it. ... show more

Great thermos for people with difficulty holding mugs!
I bought this for my 82yr old roommate.. he absolutely loves it! He has difficulty holding coffee mugs. This handle works great for him. It also keeps his coffee hot for a long period of time! This is a great coffee thermos!

Can’t use straw
It does keep my coffee hot and comfortably warm for hours about 6 hrs the down side for me isI won’t be able to use my straw because of the design of the lid. 😞

Great mug, easy to use, keeps drinks hot
I use this every day and I am extremely satisfied. I can't find anything wrong with it. I don't put it in the dishwasher like a fool because the instructions specified that I should not do that. I did that with my last mug and really messed up the finish. The handle is great. I compare every thermos to this mug. My only gripe is eventually I run out of coffee and have to refill it because I'd prefer to just continue drinking out of this mug forever. No issues with leaks. So happy to finally be using a mug that does not leak.2 ... show more

Lid does not fall off
Keeps coffee hot and water cold but most of all the lid does not fall off and spill coffee all over.

My favorite coffee mug of the year
It's one of the best thermo I've ever used! The size and handle make it so much easy and fun to drink my coffee. Also, it keeps my coffee warm enough throughout the day, which was pretty surprising! Also, so easy to clean most of the parts. The cup is big enough to clean all the way to the bottom. Disassembling and reassembling parts was a bit tricky at first, but there're some good tutorials on youtube. I am thinking of getting another in a different color!! ... show more
