I possess 3 years, I am quite pleased at the fact that I use.
It covers 180 in horizontal, but only about 30 in vertical.

It diffuses a lot of range, but they are not very powerful. It is not enough by itself to cover a full room, it is best used with other devices.

The microphone is not very sensitive (no sensitivity setting on the raptor), it will then use it when the music is loud.
If you want to use it only to loose the room, move towards a better StarFlash of the same brand (cheaper and more efficient).

Also a big negative, it is very expensive for the effects it produces.
