MYSEXYBack Stretcher Lumbar Back Cracker with Magnet Back Massager for Lower Back Pain Relief Upgraded Multi-Level Back Support Stretcher Spinal Board Device for Herniated Disc, Sciatica, Scoliosis

I actually use this back stretcher more for when I'm sitting down in chairs that don't properly support my lower lumbar. It's very durable and light weight so it's easy to move around. It works well because when I kind of forget and lean back into it, I instantly hear and feel the relieving crack of my compressed vertebrae's. Some advice with the foam piece, make sure you insert it and line it up right away before you first use this product. It wasn't staying in good at first, so I adjusted it to its highest level and back before I started using it again to stretch the foam piece out and it has stayed in with no problem ever since.

i am missing the blue middle piece...didnt recognize it til reviewing for a friend

I started trying to screw the tightening rod, and the thing came apart. It's too much trouble unless you have a toolkit to unscrew the silver screw and nut to adjust it. Trust me when I say; you'll feel sorry for purchasing this. A waste of time

Good for stretching your back, only downfall i had was it was hard to adjust it.

I don't agree with "back cracker", but it is great and easily adjustable from barely there to a high arch. Very sturdily made and should last for years and years. Great deal for the price.
