Comments: I have a 2 year old version of this. It doesn't stay at the tightness I set it to - the stretchy straps constantly pull out of the buckles - and I push it down at least every 10-20 seconds. I was so fed up on a recent fun that I ditched it behind a tree. I'm muscular and have a well-defined waist, and it simply won't stay below my waist...which means it interferes with my diaphragm while running.

Comments: The newer belt and connector are terrible. Very cheaply made and poorly designed. It broke after two weeks of use. Avoid this product...

Comments: Love this thing! Use it all the time - I hardly notice it is there. No bounce if you tighten the strap enough, and even then it is still very comfortable with the soft elastic belt.

Comments: This flat-back bottle design is bearable -- literally and figuratively -- for almost all runners, even those who can't stand carrying around a bottle in any form. It is virtually (though not 100%) bounce-free. And the company responds quickly to consumers, an added plus.
