I bought a Targus Bluetooth because my Asus computer did not have built in Bluetooth driver installed so I could use a mono headset with microphone.. Worked okay but USB is flimsy build considering the high price compared to others I later researched after it and the replacement one fell apart. Neither one lasted a year. For about 12 years I have been using a Logitech wireless USB for a small battery powered mouse which has been in and out of USB sockets on many computers and it is better made than the Targus. I consider Targus absolute absolute rubbish.
