This unit is fantastic. I bought as a practice unit and to use for solo coffee-house style gigs. It sets up easily and I love the portability. I wish JBL had a peak meter on the main, which would help with clipping, etc. This is one of the most flexible, and easily useable portable systems for the investment I have found. The battery life is great (so far as advertised) and I have used with and without being plugged in. This is a must for small venues, hotels, house concerts, and the like.
