Query: Ahhhhhh...

I originally bought the Weslo Inversion Flex System for my boyfriend, but I think I use it more than he does. It's amazing how much better my joints feel after I "return to the upright position". The directions on how to put it together could be a little more clear. It's a little bigger than I thought it would be and it doesn't fold down flat enough... but I wouldn't trade it for anything!
