Summary: I'm sure that not all of these come out of the shrink wrap and turn into junk, but mine did. It made loud grinding noises and wouldn't read disks when I plugged it in, so I dropped it in the bit bucket and bought two from another manufacturer.
Summary: The first one of these I bought worked great for about a year, after which I purchased another one. This one is very noisy and doesn't work half the time. I use this for work so will be searching for another brand.
