My stick has worked perfectly on all my computers. I occasionally pick up a used one at yard sales primarily for the memory cards, etc., and have even used the stick to clean them up and make them work again. I currently have three computers which get a monthly stick cleaning, and I advise anyone deciding on a purchase or not to definitely go ahead. The stick picks up little nasties that no other antivirus does, and I have tried them all. I am extremely satisfied with FixMeStick and highly recommend it.
Bottom Line: Yes, I would recommend this to a friend
