FAQ:
Q: Will this work with my TV or my car stereo system?
A: Sorry, this device will only work when plugged into supported Windows. Even though TVs, home theater equipment, and stereos have USB ports, they don't have the necessary drivers to support this adapter.

Q: Will this work with Mac OS X/mac OS systems or Apple Bluetooth peripherals?
A: Unfortunately, no. All recent Mac computers are designed to work with their built-in adapters, and won't work with this one.

Q: Can I use this together with my Windows computer's built-in adapter?
A: No. Windows can only support one Bluetooth adapter at a time. If you have used another adapter on the computer all drivers for it must be removed before plugging in this adapter. Any internal adapters must be disabled. We can help with this.
