I ordered them from the TV ad because of back surgery and hoped they would help. I never received them.
I wrote many e mails and got no repsonse. I should have known when my credit card company called me to verify the payment. that should be a red light to anyone. Rip off for sure.
It is not the first $40 I ever wasted and I guess i should be happy unlike others who get repeated unwanted shipments of products they didnot order.
Read reviews before ordering anything like this from tV or the internet. There are so many scams out there.
