I received my order in less than a week. The instructions on how to build and use were very clear and easy. On my first day on the trainer, I struggled a little but managed to get my legs up although not very straight or for very long. This was nothing short of a miracle as have 3 herniated discs that a year ago caused me to struggle to walk without pain. Within 4 days, using it for just a few minutes at a time,(8-10 min) I am now able to easily roll up into the legs up positions and do many of the positions on the provided poster. I can officially say that I love my Feet Up Trainer!
