CYBERNOVA Multi-Level Back Massager & Lumbar Support Stretcher - Pain Relief for Neck, Shoulder & Lower Back - Perfect for Office, Home & Car Use

Once you find the right position under your back just lay back and relax. The knobs realtbdog into you back and hot all the pressure points and really feel your back realigning. Of course it hurts and first that's because it's working. I really like how my hips even open up and feel my neck cracking and popping. Love to hear my back pop a few times too.My posture has definitely improved. I've even been told I'm standing much taller. I blow my back out constantly from sports or the gym. This device won't fix all your problems but it has helped tremendously. It relieves the pain and helps rehab my back much faster and cheaper than the chiro.I highly recommend this product. I use it twice a day for 10 mins on the first level. I've made it to the 2nd level but it's a bit high and still can't find the right spot under my back(comes with time). The chiro says to use twice a day starting at 5 mins a week, then add 2 more minutes each week for 5 weeks then try to level up.Extremely happy with this, even got a friend to purchase. He's impressed as well.
