It's Cannon Bat. (Not after-market) and it's $35 cheaper in my book that's 5 star. Thank-ya much. L.D.

It works
oh it works for upper back. No doubt about that. I wore one of these when I broke my clavicle in 3 places back in the 80's. It will get your chest sticking out. Not very comfortable but I guess it never is when u are correcting a wrong.

Works for me.
2 of 2 found this helpful works great, perfect for my 30 ft. R.V. I haven't turned it up from lowest setting and I'm at 7000 ft.
Works for me!
