The ZBoost Cellphone Signal Extender promises to improve the mobile phone reception in your home or your signal bars back. Plonk the aerial in a nearby window, connect the cable and put the unit in a convenient site and bingo, you’ve got improved cell reception on tap. They’re talking enough of an improvement to cover 2 or 3 additional rooms. Not bad. Note that you need to select the right model for your service provider. $249.99.  www.thinkgeek.com
