Got my vest last night, used it this morning according to how Dr. Warwick says to use it (found that in Amy's blog, Thanx Amy) and man I brought up some crap! And at work now still it's coming up, alot easier than normal! It'll be interesting to see how I'm doing 2 months down the line of using it. Only bad thing is that it came with a small cut in the left shoulder strap, about 1cm long, so will have to tell them so they can send a new one, that cut isn't normal right? For now i just cover it with my finger.
