I bought this product just a day from writing this review. My computer was running perfectly fine till the day I wrote this review (I'm getting a very slow startup, and was getting graphical errors and ALOT of Graphic driver crashes as I was playing games). The drivers it suggested I install were not the right drivers, some were actually older than the one I had. The customer support appears offline for me every time I make a attempt to request a refund. It keeps telling me that my support ticket was declined. Don't trust this, it isn't worth the money. Another odd thing... As it was installing a "update" for my graphics driver ( Which my radeon Desktop app said was already up to date) It installed with no issue at all. The screen for me normally flickers when radeon installs it, also it pauses about 25% through, but this software didn't pause at all, instead it was just a continuous install from 1% to 100% as if it wasn't installing anything for it at all.
