Q: I've used this switch as an extension with three external hard drives. It gives me four additional USB slots instead of one.

Q: If you are looking for a fast pace, action, and adventure story than this novel can fill your need. This book kept me awake for about 5-6 hours without putting any effort at all. It's just too good to put down. While reading it, I was able to learn how the author researched her subject matter. The details she included give an inside look into the time period of late 1800s England. Not many books that cover so much information do it in such interesting way.

A: Good Review
****
Q: Do not buy it unless you have a very small TV or dvd player. It's like those "portable" DVD players for kids. Very bad sound and video (blurry). Poor remote too. If I can't return it, I'll put on the goodwill pile right away. You shouldn't waste your money.

A:
Bad review
