@Horton, Unfortunately not exaggerating MY experience with the Powervest. It's been a while since I used it, but I remember having the straps too short initially, and could barely get out of the water without going out the front. I agree with @Milford, people that haven't had a major injury don't understand the worry of re-injury and another long rehab. I still think it's a good way to ease yourself back into things, just take it easy until you figure it out.
And, no I don't type like that, this is the only site my phone (android) does that on. Guess I need some tech support on phone settings.
