Feature:
This product REQUIRES a propietary adapter in order to work, I feel that the manufacturer made a big mistake with this

Quality:
It looked like good quality poorly designed equipment... take that as you will. the proprietary connector used 4 very thin pins with no secure lock system for the cable, it would break very easily.

Value:
The website advertises 20 selectable frequencies... but that just means that one is hardcoded, and there's 20 totall.

Desirability:
no flashy lights... no cool display, it's dismal.

Sound:
The sound of this product couldn't be realized, since the attennas are on the wrong side of the rackmount... they are forced to cross, which is not good for diversity spread systems

Support:
They were friendly... there is no toll-free number however, and the only thing they could tell me was.. yes, you need to buy our special cable to make it work with a guitar... or any instrument.

Overall:
I actually just requested an RMA. I wish I knew the cable was required before I bought it... and I'm sorry stating that you should buy a wireless mic or wireless essentials cable to complete the system on the website doesn't cut it.. it needs to read.. YOU NEED THIS CABLE FOR IT TO WORK with a link to it.
