We had to buy this dongle to connect our bluetooth headphones as our computer couldn't use bluetooth without it. At first we thought there would be constant interference with the mouse and Bluetooth dongle (every time we plugged headphones into that port, the mouse stopped responding), but a tech-savvy person was able to fix the issues. Overall, both the USB dongle and the wireless earbuds worked very well. I would recommend people to get an updated version in case their old model of the same item doesn't work with newer models of computers or laptops.
