I purchased a britebox dermaclear, they cost around 200 but they say no risk as you have a 60 day money back guarantee. After a few weeks I knew it was not working and was not going to work. I emailed them about the 60 day money back guarantee and received "out of office" (not sent automatically though but manually) and have been getting that reply ever since, I'm guessing then that the 60 day money back guarantee is pie in the sky!
