Today for review I've got what is probably the world's smallest Bluetooth USB adapter, it's not much bigger than a dime, and that's only because of the USB part of it, the actual Bluetooth chip is a fraction of the overall size. It's called the Super Mini Bluetooth v2.0 + EDR USB Adapter, but don't let it's diminutive size fool you, it's fully loaded, being Bluetooth v2.0with Enhanced Data Rate it allows for longer range and faster file transfers.
