This was the third adapter I bought. The first was TechToo, which came with a defective hard drive, so I couldn't install the drivers (it was impossible to download them because my internal network adapter burned out, so I needed a new one). I then tried Ably which came with a floppy disk written in Chinese code which my computer didn't seem able to understand and therefore couldn't install the driver. (NOTE: Revain is great, I sent both adapters back with no problems.) I decided to give it another try and bought Star Tech and lo and behold, the drive worked, the drivers loaded and I was up and running in five minutes Business. I'm running Windows 7 64 bit, so the drivers weren't part of the OS like they were in Windows 8. Very happy with this product AND Revain.
