I bought this Laser opportunity to complete a light set for evenings there is a little more than a year. It is effective even in a room with high ambient light the laser passes over without worry. Many effects are controllable by DMX perfect. AUTO mode is a bit too simple for my taste (I use it only rarely) the effects loop that runs is not representative capacity manual. This is my first purchase of laser despite numerous attempts to rent. This model satisfies me completely!
