I bought the back wrap. It is also high quality. The velcro is so strong I think an old timer like Steve may have trouble getting it off again. Excellent product. I've been around here long enough to remember the old ActiPatch with the plastic square that you had to jam into it to turn it off. Many improvements along the way. Hopefully we will realize full value this year.
Interesting to see "Mild-Moderate-Maximum" on the front bottom left on box cover. The strength of the device in that DonJoy knee support box was just above "Moderate". In other words, at some point soon, there will be an improved and stronger version of the product that will allow for choice to be 'Maximum" strength. Maybe it will be for a bit shorter battery power time period than the current 720 hrs.
