Wireless signal for rear speakers on surround sound

I've had my surround sound system for a couple of years now and up till my current residence have been able to successfully run and hide wires. With my current setup I couldn't run the wires without having them across my floor in my living room...so I did some research and found an awesome solution. I got a wireless transmitter for my rear speakers. It works pretty good. The brand I got was RocketFish. I got it off of Ebay for around $50. Here is a review. There are a couple other options available too like Think Geek's wireless amp

It definitely helps with a signal and allows me to utilize my surround sound again.
