Product review (4 stars): Actually works as described
I have tried several other brands, none have made a difference.  This actually worked great.  The only reason I gave 4 vs 5 stars is that there are 4 gel discs that go inside the pads. You have to peel them off and place them inside.  One of them tore inhalf trying to peel it off, so be very careful.
Otherwise...great product, highly recommend.
