Summary: When it is working, it works at 300mbs like advertised but almost daily while I'm using it, it just willshut itself off as if I unplugged it, and it's nothing that the computer settings has to do with it, it's for sure a dud from the factory Didn't last long so only gets 2 stars
Summary: These things are a God send. I use them every day. Only had a problem with one. I left it pluged in by accident and put the PC in the car. It was at a right angle. It still works but not real well.
