I need a low profile water bottle solution and thing this may just fit the bill. But, I am curious if anyone is using them. One of the reviews from a roadie sounds like they pop off easily. If they pop off of a road bike they'll surely be gone quick on a MTB.

Anyone using these with success and not having them pop off all the time?
