Good device that coul be great with a couple of tweaks.
Strap is of good quality and relived the medical condition. Had to make some modification by removing a Velcro parcel at the end of the strap that rubbed on my arm. The stap also required extra attention and technique to keep from creating a fold in the material when tightening. Exchanged email with company so hopefully future generations of the strap will improve these issues.
