Rocketfish wireless system for rear speakers

I am posting this here and in the speaker forum as I am not sure where it belongs.

Anyways I noticed the BestBuy ad this weekend has the new Rocketfish rear speaker wireless system. I am curious if anyone has tried this with their receiver. I have wood floors and a high back wall so running speaker wire is impossible. I have used the Kenwood receiver with mixed results and wanted other options. Curious to hear feedback on this.

Thanks

only part that concerns me is the volume knob on the back and how loud you can get it while calibrating your system. I like the Kenwood unit but the speaker wires are fixed and terribly small. the Rocketfish allows you to use higher gage wire.
