Review (3/5): Hard to apply
I found this product very hard to position, and even after practicing, still can't quite do it. Once, I actually got it in the right place, and it does work well if you can do that.
The assumption is that your droop is just in one place, but my droop goes in many directions. Not as useful for that.
Still, it was very inexpensive, so was worth trying for me.
