Bought 2 for vocal+ guitar setup in bigger venues. They seem well built, sound is crisp and powerful (a bit short of bottom end, needs a bin for dj use).
Could do with a mute input button or at least an on/off switch, you have turn down the Db dial to 'mute' the input.
Speaker turns on as soon as you connect power.
One more minor issue, the side handle should be rotated 90 degrees (vertical, like EV's) to make it comfortable to lift onto a stand or carry on it's side.
