Pros: Fairly cheap in price, has a good number of buttons and adjustable DPI.

Cons: Construction is very weak/flimsy. For a good two weeks the left button squeaked when clicking. The scroll wheel was also too sensitive, often scrolling two or more times the intended amount with the same amount of pressure and software sensitivity other mice have no issue with. Just today, a few months since purchase, the scroll wheel stopped working entirely- it doesn't even make the sound mice usually make when scrolling. Middle click still works for now, but it's still disappointing for a non-abused device to wear out so quickly.

Overall Review: If you're looking for a cheap mouse with a good amount of features, this is a decent choice. Just be aware that it's cheaply made and apparently wears out quickly.

Pros: It boosts signal! (0-0.4 bars of 2G becomes 5 bars of 3G)

Cons: Range is "up to three feet" from device on paper, which is kind of useless on its own. Range is "touch the signal booster with your phone or you get nothing" in practice. Unless you use speakerphone or a bluetooth or wired headset for phone calls exclusively, it's entirely unhelpful.

Overall Review: I'm in a dead zone for my service provider (BlackBerry from Straight Talk, uses Verizon towers for some reason), and without it I get maybe one bar of "1X" (2G?) service in very certain areas of my house, and maybe a second bar in some areas outside. Using this device, I get a full 5 bars of 3G service... if I set my phone on top of the device and use a headset for any calls made/received. I'd hate to imagine trying to use something with so little effective range in a car! The box far overplays the range and usability of the device. I can't say it's worth the price for such a useless range, but it works ok for a "I need more signal at my desk" application.
