This is a very good unit. It's very simple to operate and is built very strong. The sound is excellent and there is plenty of headroom for when you have to do louder shows.
The same day it arrived I used it at a hotel gig with my quartet with one FOH speaker and later in the evening on a show with a 15 piece band with lots of floor wedges. It handled both extremes very well.
It has all the features I wish that my Rolls PM50s and my Behringer PowerPlay P1 had. I wish it had combo jacks on the inputs but a D.I. box or adaptor works fine.
The battery life is pretty good. My first gig was from 7:30 pm to 10:00 pm and the second was from 11:00 pm to 2:30 am. Add that to the time I spent with it at home checking it out and I'd say, that It's good to know that with a fresh battery that I never have to worry about this unit going down on me in the middle of a performance.
I'm giving this unit full marks for what it does. The price, build quality, features, sound and portability are all excellent in my opinion.
