Very good thermal efficiency - contents stay hot for ages. Also love the fact that you can pour without removing cap entirely and ot doesn't dribble everywhere. Not the cheapest around but you get what you pay for.

The Thermos kept my coffee piping hot for hours. Durable design. Built in cup.Happy!Tip: Before you fill it with your desired content pre-warm it with boiling water.

I had an accident a few years ago and lost my Stanley bottle. Found this one at Academy Sports. Looked at it and decided not to buy it. Walked around the store looking at things, my wife told me I might as well get it so we went back over to that department to get it, looked at the Stanley bottles again but got this on instead. Best choice I have ever made. This bottle keeps coffee HOT longer than any other one I have ever used. I am going to Academy in the next week or so to get a new one. This one is 7 years old and has not been treated the best, looks kinda rough. Best vacuum bottle I have ever had. Thanks Thermos.

Bought this to be my coffee mug, water glass and growler. The handle does have this lip part, that you can rest your thumb on when you are carrying it open to keep it upright from spilling.Now, under the top part of the handle is very user unfriendly. Hard edges which should be rounded and hand friendly. You'l see.
One of the pitfalls of ordering online is you don't get to see, feel or see all the features. I thought this item had a collapsible handle like older Thermos so it takes up a lot more space than expected.but the quality is 100%
I looked at lots of thermos bottles online before I decided on this one. I purchased it only a couple of weeks ago and the cup has already come apart. The design has too many places water can get in when washing it for it to only come out later when you are trying to use it. The last thermos I had isn't available any longer so I had to choose another one. I thought this one would be a good choice but I would not buy it again. Price was expensive for what I have already experienced with the product.
I've had mine for twelve years and I've bought two of them as gifts. In both cases to replace a very inefficient green vacuum bottle. The recipients were thrilled. The most recent one was tired of watching me drink hot coffee at work while she was drinking coffee that was barely above room temperature. I recently had a stranger walk up to me and point at my Rock and say, "Hey, I have one of those too! Aren't they great?" I've sometimes wished they came in a larger size for travelling but why not just carry two? They aren't very expensive.
I've used this Thermos for years. I do construction so it's not usually kept in the best environments, but even when I get home and dump out any leftover coffee or tea it's still hot 12 hours later. It's a little fragile. I dropped it so now the cup doesn't sit quite right, but who cares? Highly recommended.
I bought mine around 2004. I use it everyday. Though being 16 years old it still looks and works as if it were brand new. I make a pot of coffee in the morning and pour it on the bottle and it stays hot all day.
Have had several replaced on warranty. Great while working. No apparent reason for failure. Purchased different type though same brand this time. Hoping for longer function. Appreciative of replacements.
