What I got was a little 6x6 inch tool bag delivered! They claim this was all I ordered! How could this tiny bag help my knees? Was told not to send bag back on return mail as it was not the same place! It is a scam and they seem to just send you a much lesser product! It was not a lot of money thank God but they make a lot of money doing this to everyone! I will report them to the right people! I am so mad about this scam!
