"zBoost YX300 Cell Signal Booster"4.5 starson by biggestgreg
Pros: Easy to set up and really works!
Cons: You have to keep the antenna a minimum distance of 6 feet from the base or it doesn't work (but the red light comes on to tell you so).
Summary: The YX300 works great for my desk area in my house since my one window is over 6 feet away from my workspace. It consistently increases my skimpy coverage area of 1-2 bars up to 5 full bars! I use a Blackberry Curve and this works great for it. It does the same for my Verizon Wireless Air Card!
I've used it at hotels when I travel and it works great in bad coverage areas there as well.
The only reason I didn't give it a 10 is because you really have to be sitting near the antenna for it to work well.
