Wireless stuff has been around for some time and they have not figured it all out yet. That's up to you if you want to try a system or not.
Im not a fan of anything that's wireless, been burned one two many times. That includes truck camper jacks and air bags :M
I have had a lot of wireless issues communicating between the two devices in any type of wireless system. I tried a wireless camera and it fluttered too much to the point where my eyes are still 'blinking' and I don't have the system anymore. :)
here is a thread to read for more info.....
