I bought this mainly as a PA for smaller gigs with voice guitar and clarinet. I wanted something very small and light. I'm hoping I might even be able to transport it by bicycle sometimes.
Used it a few times and very pleased. It's perfect for solo playing with a single mic and guitar plugged in, with the extra mic for two of us I use a little mixer, just upgraded to a Behringer 1202fx as that will allow me a touch of reverb and an extra mic if we need one.
Sound is good and loud enough for a cafe gig, I would be quite confident with up to 50 people if they were listening rather than talking and maybe more in the right location. The on-board mixer is just right for solo work and the unit really is tiny.
My only reservation is that although it sits on a mic stand it's a bit heavy for the cheap stands I have so the setup does sway a bit. Also the mounting is designed for a tilted monitor. For PA where it should be more level I've worked out a way to use a boom clamp to tilt it* but it's not ideal. I might buy a proper speaker stand and make a plate for the top to fit at the right angle.
But for the price and the tiny size it's just great. Might even buy a second one.
*The kit includes a short threaded tube that allows booms to be fitted on top of the speaker when used as a monitor. I don't think many people use that for its intended purpose, but clamp it where the boom normally goes in a mic stand and you can attach the speaker mounting spigot on there and have complete control of angle, at the cost of moving the weight of the speaker a bit off-centre.
