Really keeps stuff hot!

I bought this as a gift for my honey bunch, and he said it's the best travel cup ever.  It keeps coffee hot for several hours and doesn't leak.  From a functional standpoint, it's awesome.  Esthetically, there are some challenges, since the paint wore off within the first year, but it still works fine.

At first I wasn't thrilled about how slim this is because it doesn't fit well in my cup holder. I fixed that problem and I love this!  I wish all colors were available in the 20 ounce size.  It works so much better than my knock off Yeti mug! I can put it in my bag and not worry about it leaking!  Best of all, it really does keep things hot far longer. Solid construction, locking lid, easy to clean...this is worth the money!

Holy CRAP!!!!! This travel mug is AMAZING! hot coffee will stay hot for quite a long time and has stayed warm for up to 6 hours at least. great mug! the anti spill function has saved my butt more times than I can count and is truly and honestly ANTI-SPILL. I can fill this mug up and turn it upside down and nothing comes out. its fantastic!

Absolutely love this thermos! I bought one for both of my children (1 yr & 3 yrs) and so far they have held up very well even though they have been dropped multiple times. They keep water cold even while we were at the beach all morning in 90 degree weather.

This thermos flask is really good. It keeps my coffee rather hot for nearly 6 hours. And yes it does not spill the contents if titled, however, why would one tilt a container full of hot liquid. Though please be cautioned while sipping very hot content very soon after pouring it in the flask, for as I said the liquid retains the high temp for long. Very good travel accessory.

I was very skeptical that this could truly keep things hot/cold for as long as it promised. I tested it first with hot water. After 14+ hours, the water was still steaming when I poured it out. Then I tried ice water and there was still ICE in this after 48+ hours! I have been so impressed, I want to own one of every color! :)

This is one of the Best thermos I have ever had. Use it for soups and stays hot past lunch. Worth the price (it's a little higher than others, but maintains its heat so much better)  I use it almost daily. Comes with a spoon as well :) From what I read in other reviews, it has a long shelf life as well.  No spills or leaks either.

I have been looking for a coffee mug that would keep my coffee hot longer. The thermos is great, I fill it up around 4:30 5:00 am when I leave for work and at 11:00am its still hot if I did not finish it yet. Really good and definitenly worth the money,I just wish this specific mug had rubber around it. Mug does not get hot when you hold it, just would be an advantage for holding it.

Really keeps things cold or hot for a long time. I left ice water in my car (really hot day) and there was still ice in the thermos 8 hours later!

I love this thermos! It keeps my beverages hot or cold as one would expect from a thermos.  I had steaming water coming out of it after a full day of work! Sometimes, you think products will never even work despite manufactures claims!

The construction is great and I feel it is of high quality given today's often hurry up and make it cheap standards.

Excellent thermos! I use it for tea and it keeps it very hot 24 hours later. The only problem i had was the plastic cup and the tin around it seperated but I was able to glue them back together and have not had a problem since.

We absolutely love this thermos!  We use it for our baby girl every time we go out.  She's gotten picky with the temperature of her formula and will only drink it hot so we had to start carrying hot water with us to heat up her bottle.  We usually carry this one filled with boiling water along with the smaller thermos.  We carry the smaller one in her diaper bag with boiling water filled about 3/4 of the way so that we can just set her bottle in it to warm.  This bigger one we use as a backup for extra hot water.  When we put boiling water, it will keep hot for at least 14-16 hours.  Once the water in the smaller one gets warm, we refill it with the hot water from this one.
