I have given a review once and either they took it down or I can't find it. I see a awful lot of one stars and they all say the same thing that happened to me NOT getting the reward money after making the purchase. I have emailed them at least 6 times and they refuse my purchase. I threatened to sue them for false advertising and I believe all the negative one stars should sue them. What really needs to happen is that they need to be shut down.
