Review on ASUS USB BT500 Bluetooth Backward Compatible by Darrell Beecher

This tiny key far exceeded my expectations. I was convinced that nothing could work as well as built-in Bluetooth. I use it all the time and I haven't had a single signal drop. No hiss, no volume changes, no problems. I threw away the packaging, so I don't remember the actual numbers, but the signal goes much, much further than ASUS' own citations. My previous built-in Bluetooth signal would cut out if I went too far around a corner into another room. This ASUS dongle sends me a signal through every wall in my apartment - even outside on my balcony. It may help that I placed the key on the top of my PC case and not on the back facing the wall. In any case, it works very well. I highly recommend this ASUS Bluetooth adapter.
