Only at Best BuyThis Rocketfish™ RF-WSW312 wireless transmitter/receiver kit makes it easy to equip your home theater system with a wireless subwoofer (not included). Up to a 45' wireless range allows flexible speaker placement.
I purchased this in August, and initially it seemed to work. Then I started noticing the absence of a subwoofer sound. When I checked the wireless transmitters, the LED's were red instead of blue, which means they had no connection. Because the devices go to sleep if there's no subwoofer traffic, it was difficult to know whether the wireless, subwoofer, or other devices were to blame, the problem took a while to sort out.
After working with a support technician at the Geek Squad call-in number, who showed me how to reboot the device and reconnect, I got the devices to connect for a short period and then disconnect. As a result, I brought the kit back to my local Best Buy, where I was able to exchange my device for another. But the problems persisted.
Of course diagnosing the problem took longer than the 15-day return period Best Buy offers, so I can't even return it.
