Query: Review of Sony Wireless Remote Speaker

The design is very clever, combining stereo in one unit. However, it did not work well at all. It was very noisy with a hiss. And, the controls were fussy, not the set-and-forget I had hoped for. I believe the transmitter on this unit was faulty. I have another 900 MHz transmitter which, when on, boomed through. The weak signal and the fussy controls prompted my return.
