I've had the ATM2 since February '07. It sparked my interest at a PT conference when it significantly helped the back pain I'd developed after the 10 hour drive to the conference. I use it extensively to help my patients with all type of spinal, pelvic, and hip problems.
I've started to call it my "WOW" machine because ~9 out of 10 people say exactly that when they experience their improved mobility after only a few minutes. It's even more dramatic on people NOT in pain, so they quickly see (and more importantly FEEL) how using it can and will improve their athletic performance, especially swinging a golf club.
It's simple, functional, and gets RESULTS. I am also impressed with BackProject's support and training.
