I am using it. In fact just got back from setting it up at the supper club where I play on Wednesday and Thursday. I've had it about a year, and I use for small jobs.
It is a really neat little system and capable of carrying crowds up to 50 or 75 people.
The built-in reverb is good (only one effect). It's easy to transport, set up and take down.
Any specific questions, let me know and I'll try to answer.
By the way, mine is becoming available soon, as I recently acquired another one through a trade.
