After we installed our Home Theater system, and spent way too much money having all of the speakers wired through the ceiling and walls, we realized that the subwoofer was way to close to both the wall and a furniture piece (causing BOTH to rattle)! We thought we were out of luck, and since the walls and ceiling had long since been closed back up, we thought that buying a new wireless subwoofer would be the only solution. Problem with that, aside from just spending A LOT of money on a KEF reference sub, was that our receiver was located in the next room, in an AV closet, and wouldn't have direct line of site to the subwoofer (which, from what we saw online, most/all needed). Needless to say, we were very frustrated... That was, until we found this cheap (but effortless/amazing) solution!!!
This thing works EXACTLY as promised, and then some. There's been one or two instances where it lost the signal, but it is such an easy fix that it's almost a non-issue (just need to press the link button on either the transmitter or receiver).
Overall, I can't say enough good things about this product... I was hesitant to buy a RocketFish product (only because I had never used them before), and I must say I was wrong to be!!!
