I first tried this product in the hotel gym while traveling. My back and shoulders had been particularly painful because of many long hours at the computer. I had been considering booking a massage in order to try to ease my tight muscles. But I tried this machine and instantly loved it. Looked online for where I could buy it and located a dealer near my home. After returning home from my trip, I instantly went to the dealer and bought it. It has been great for me. I had a disk removed from my lower back many, many years ago, and no spinal fusion was done. That, combined with age, has really left me with a compromised lower back. Sitting at the computer has left me with a compromised upper back and shoulders. The Stretch Trainer has really helped me feel better, feel more limber, and sleep better. Worth every penny.
