It's the perfect sized water bottle. The water bottle is big, but not unwieldy. As a foam roller it works really well. And the sleeve slips on and off easily, so washing the water bottle is no problem.
Got this bottle as a gift for a hard to buy for coworker-and he loved it!
I got this as a bit of a joke but now I steal it from my girlfriend when we go on trips. It's a really effective roller!
It's a good size for daily use
I was worried this would be really bulky but it's not. It holds a good amount of water but still fits in my cup holder and is small enough to easily travel with. Because it's diameter is smaller than the average foam roller you actually get a bit of a deeper massage, which is nice. Really great overall!
