Helps very much with my back but hurts being stabbed by middle prongs
These guys almost had the perfect device to reduce my back and neck pain but as always you had to mess something up and that someone is the middle V and balls that stab me in the chest when I use it for my mid back they're almost unusable for what the purposes are for them being there and hurt when using the device other than that a perfect device for my size and body tight which is 6'3 220
