I remember the first time I purchased one of these, which was several years ago now. I was totally happy with the results. The computer I used it on back then was in total conflict with me before and this "simple little black USB" cleared up all the issues I was having at that time!
I told my son about it and showed him how much better my computer was running. He was amazed and still a bit skeptical. Then his computer went a little bit so he tried it and it totally fixed every issue he was having with his computer.
I know it had extended the life of my old laptop by at least a year!
A great product for a great price and it is quick and easy...
Bottom Line: Yes, I would recommend this to a friend
