This only has a typical range, I bought it because it was advertised up to 300ft but it doesn't go further than other Bluetooth devices so it's the Extra charge not worth money, in fact it's a lot more than other devices with no benefits that I can identify. I raised it about 5 feet on the stem to give it the perfect amount of headroom. for RF, which brought no improvement. I bought this because my IOGEAR USB 2.1 GBU421 bluetooth micro adapter was only 30ft at work when there were intermediate structures and it's no better and much bigger and more expensive than the GBU421 so I'm returning it. I tested it with Sony DR-BT100CV and Motorola S305 with the same results. Bottom line, it's not worth the extra cost or size, you can get the same performance for less money and with a much smaller device.
