I was concerned by the price, it seemed a bit cheap to me but Chauvet is a good brand so I trusted it. When I actually saw it I was even more concerned as it's tiny!
Don't be put off by either of those things, we unbowed it, plugged it in, it warmed up and proceeded to fill the stage in our village hall admirably.
It's not going to flood the O2, but you're not paying for that. For a disco or our use, on an 8 5m wide by 5m deep stage, it's great. Continuous first run was 25secs until it needed a breather, by which time we couldn't see each other at arm's length.
As long as you're not expecting something which will belch out enough to obscure a battleship, you shouldn't be disappointed in this little pocket rocket.
