Dual Hand Warmer Functionality is Awesome
I absolutely love this bottle. Not only does it keep my coffee warm, but it also scores high for doubling up as a hand warmer. As someone who is prone to back pain on long road trips, I no longer need to carry ice or heat packs to relieve my aching back. By simply shaking the bottle, the outer surface is activated and it serves as a hot water bottle to relax my muscles. I also love the simple streamlined design and compact handle that makes it easy to carry and store. Well worth the price and I would highly recommend it.

Doesn’t hold temperature
I like the look of this bottle, but that’s it. Cold water gets lukewarm pretty fast. Can barely stay cold for 90 minutes. I wouldn’t buy it again.

Great cup!
Great size, love how warm it gets, especially how cold it’s been. Fits in my cup holder and it has a handle to make it easy to carry.
