The Mogo Dapter is one of the smallest peripherals we've ever reviewed – it's a tiny device, no bigger than the end of a thumb, with a USB plug at one end. Once plugged in it gives your computer full Bluetooth capabilities.

It's true that most notebooks now come with Bluetooth, and if you're using a desktop, saving space isn't such a big issue. But for those with Bluetooth-less notebooks, the Dapter is an excellent idea. Since it hardly sticks out, it won't get yanked out easily, and can be left in when the notebook is stored or carried.

It comes with the required software on a CD, which includes a nifty graphical display of nearby Bluetooth devices, and it will work with Mac computers as well as PCs running Windows XP and Windows Vista. At £15 it's certainly good value. If your notebook didn't come with Bluetooth, this is about the best way to add it.

Vista compatible: Yes
