Can having a Quicky boost your Wi-Fi range?

Get your mind out of the gutter! I'm talking about the Quicky Jr II USB wireless signal booster, which is a little USB dongle / antenna that plugs into a USB port on any Mac that is running Mac OS X 10.4 or newer. This little device, from QuickerTek, purports to let you wander up to three times the distance you normally can, and still receive a nice, strong, and encrypted wireless signal.

The US$89.95 Quicky Jr II comes with an easily-installed USB driver that lets it work with your 802.11n/g/b networks, including those that are powered by an AirPort Extreme Base Station. While I'm usually dubious of any device that claims to increase wireless range unless it is pitched by the late, great Billy Mays, the Quicky Jr II appears to be just what it says it is; a powered USB Wi-Fi antenna. In theory the larger antenna size and a built-in USB-powered amplifier could help boost the signal, then route it to your AirPort circuitry.

Rather than speculate on how well devices like this work, I'd like to ask our readers. Do you have any experience with this or similar products? Do they work as advertised? TUAW wants to know.
