Great product, I sprayed some lubricant on the outside to slide it in easier (not needed, but makes it smoother) my only gripe is the size available, I wish it would hold 10-15 more oz. other than that, it's great!

Excellent

I love this system for use on bike. But, it is tricky to get into the frame. Once it's in...I find it easy to use, easy to fill during the ride, easy to take out and clean. I would recommend it but caution that it takes some finagling to place it in the frame correctly.

Quenches my thirst when I ride my bike. Good quality item.

Tough to fit in the bike. Once in, tough to fill up. Bite valve sucks. It less falling off.
