Purchased today, but for domestic use only (it is in my little throne room of 17 m2).
Cheap and friendly, powerful for the game prizes.

I can not find it particularly noisy (especially when there is music).
For cons, the microphone is not sensitive enough. I can not use the music mode (in apartment).
It must be very effective against the evening.

For 130 euros, a 40 mW green laser, DMX-controllable, it is a treat.
Very good value for money.
