I use it for about one month and already with 4 prestas!
It works well. Must be enough smoke to draw well the beam but the power is there.
The volume is very good here well filled room.
I managed from a computer equipped freestyler, it took a little retouch fixture, but now it is happiness. Either I manage myself, or I freestyler active since the car or musical mode.
Summary: few weak point for me, apart from it is not worth a 1000mw in terms of power.
Strengths, creates the volume (especially on forms tunnel type, tubes or triangle) and multicolored changes that follow.
I find the value for money very interesting.
From experience, I will do it again and then a choice 1w range above.
I plan to buy a second soon to play on symmetry and more volumes.
