Back Cracker, Back Cracking Device(4 Level), Back Stretcher, Adjustable Multi-level Spine Board, back cracker board, Upper & Lower Back Muscle Pain Relief for Herniated Disc, Sciatica, Scoliosis

I ordered this after seeing reviews and videos of how much it helped with back stiffness and pain. It doesn't so much crack your back as many claim, but it does give your back and much needed stretch and helps with stiffness and soreness. I definitely recommend starting at the lower level of arch before trying the maximum. It seems sturdy and well made, though I'm not a fan of the little pressure pegs, they aren't a deal breaker.

Layed on it like I was supposed too and didn't do anything.

I was hoping this back device would ease stiff back muscles. What I found, was a hard stiff device that hurt rather than sooth. There are several settings that can be used to raise or lower the high point, but even at the lowest setting it was too stiff. I think if the system had more flexibility to it, the pressure on my back wouldn't hurt as much. Someone else may enjoy the firmness of the device, but it's just not for me.

It actually cracked my back. Not like I’m used to by having someone push down on my back, but definitely relieved some tension on my spine. You can use it on the lower and upper back. The fourth notch is a big stretch and the cracks I got felt so good.

I tried this thing on various settings and my back didn’t pop. I could feel it stretching my muscles, but the little plastic spikes make it difficult to relax entirely. I honestly feel like it put me on the edge of my back going out at anything higher than the second setting.With all the hype for similar products on social media, I was very hopeful about this thing. It just didn’t live up to the hype. I get a much better stretch and more popping of my spine using a yoga wheel.
