Don't buy anything less! This is the best!

by Chaz Antonelli on 3/15/2012

I bought one of these five years ago for over $30. After a heavy clout damaged it, I purchased a (cheaper) replacement only to discover that not all USB Bluetooth dongles are the same! This is the best for the lowest price. When other dongles don't always work with all services or devices, this one's tried and true!

The IOGEAR USB 2.1 Bluetooth Micro Adapter performed as advertised with no surprises on my Toshiba laptop running Windows 7.

Product Overview

The IOGEAR Bluetooth USB Micro Adapter offers Bluetooth connectivity at a fraction of the size of normal Bluetooth USB adapters. About the size of an adult fingernail, the IOGEAR Bluetooth USB Micro Adapter allows users to connect to all the latest Bluetooth devices like cell phones, PDAs, mice and keyboards. Because the Micro Adapter is so small you can easily plug it into your computer without blocking any surrounding USB ports. The Micro Adapter also features Bluetooth EDR (Enhanced Data Rate) technology for transfer rates that are 3 times faster than traditional Bluetooth 1.1 and 1.2 adapters.
