Is anyone familiar with the MUSYSIC: MU-12PA?

I am looking for a reasonably priced PA system to use for my shows. This one just seems a little too good to be true for the price. Can anyone that has had experience with this brand, chime in. Or if you could recommend another unit at a similar price range. Obviously, I need it to have a wireless headset and input for music. There is a 14 day return policy and you can purchase up to 3 year Squaretrade warranty. I am just not sure whether to try it out or not. Any info would be greatly appreciated.
