This = IOGEAR Enhanced Data Rate Class 2 Bluetooth USB Adapter Ranges up to 66 FeetHave two LTs (Thinkpad/Dell) both of which claim to support bluetooth.Also have bluetooth logitech mouse which should work with them. (And a bluetooth headset)Could never get them to pair (either LT). Googling pointed many frustrated users.Bought myself two IOGEAR USB adapters - one mini (longer range), one micro.This one - worked only with Dell LT. Did not work with thinkpad. Although all drivers are installed.The IOGear Bluetooth USB Micro Adapter (GBU421) worked fine with both LTs (and both mouse/headset), and being compact, no need to remove from LT.
