I don't usually write reviews, but this time I had to. I have suffered from back pain since I was around 11 years old (I'll be 40 in a few months). I can't even remember what it feels like not to be in pain. I have tried everything from skeptical as seen on TV devices, inversion tables, to pain killers and Yoga and meditation (Anything to stop the constant pain). So when I saw the Stamina Inline traction system I though..OKAY yet another device with high hopes that will probably end up at a yard sale some day, but like all the others before I decided to give it a try. I COULD NOT BE HAPPIER WITH THIS DEVICE. Of course there are a few little things that are not perfect, and the construction is not aircraft quality or NASA certified, BUT for the price you can't go wrong. I owned an inversion table for 15 years and rarely used it. It was time consuming to take everything out of my pockets, find the space for it to swing wildly in the air, clamp my ankles in and have the blood rush to my head. And of course it never seem to work on the area that was in pain amd seemd to cause more pain in my ankles and legs than anything else. The Stamina is different. It's simple and fas., I can use it 10 times a day if I want, for a quick pressure release or a longer stretch. Best yey, IT ACTUALLY TARGETS THE RIGHT AREA. It takes a little getting used to and a little experimentation, but you can adjust the machine to stretch exactly where it needs to stretch. As a hint... Adjust the height high on your waist and the belt/strap close you waist to target the upper back and lower the height and move the belt back for lower back, somewhere in the middle is the sweet spot that gets the entire back. Hold your elbow close together for the upper back and farther apart for the lower back to allow more of a forward stretch. Bend your knees for lower back, straighten them for the upper back. So if it isn't stretching the right spot, experiment until it does. This isn't the machine to end all of your back pain for good, but if you are like me and live a life of constant pain, and have known your chiropractor and acupuncturist longer than your wife or husband, and know more about your massage therapist than your brothers and sisters, the Stamina InLine will be a great addition to your arsenal of healing if you take the time to learn how to use it. It's strong, affordable, reliable, simple, strong (I'm 6'0 200lb) and effective. I am completely satisfied and would give it a higher rating if I could.
