I'll start off by stating that by no means is this the greatest sounding monitor out there - but look at the price! You kind of know it already. If you have a digital desk (or a really good multiband analog-EQ) you can tune the monitor to get the worst feedback-frequencies out.
I do, however, like the build of the cabinet, it's easy to get a hold of and carry around. The connectivity is pretty standard with XLRs in and out. The power is pretty good too, but feedback becomes an issue pretty quickly. And when tuning out all the feedback, the monitor sounds, well... unclear and artificial.
I use this on my troubadour-gigs and it works well enough in those settings. I wouldn't however use it in a loud rock band-setting.
