but a pain reliever. The Super Vital Long-Life was reduced, so it also makes Knacks noise in the prescribed 12 minutes. Okay, not so bad! I concentrate fully on my back and try to achieve something with power of my thoughts. I am 36 years old and weigh 113 kg, cycling, gardening, that is part of my everyday life. Just as a jump-off in the back. God forbid, but very bad it has not caught me. Still, I need a little relief and for the Super Vital back trainer is just right. Regular use promises relief, I can confirm use after 2 weeks.
