I purchased QRB from the infomercial (the one and only infomercial that "sold" me) about a year ago. It does work but not as well as on TV. I used all of the remover and did not complete my project. I think it was too cold for the remover to work effectively. To purchase more remover, I called QRB to order more. The remover is way cheaper through the company that it is through the infomercial, especially if that's all you're interested in. I suggest giving QRB a call, they're on the internet. Good Luck!
