I must admit I was a bit skeptical about this tiny bit of metal when it came in the mail. I plugged it into my laptop that I got a year ago, and it only had one issue. Then my husband plugged into my old dinosaur Windows 7 computer that I haven't used in a couple of years because of the issues it had. It took 12 hours to run and fix things, and when I went to use it, it was SO much better!! I highly recommend this to anyone that has issues with their device.
