I use it for 3 years.
The colors are nettent and change color / gobo wheel is precise.
I use both and I have some concerns about one of the two. Occasionally, the wheel locks up and I can not change the colors (the butts of the wheel locks), but I rarely ca.
The engines of the mirror are very noisy (hiss rather unpleasant) and get along when the music is not very high (on slow).
The price is quite high especially for a scan has a single wheel.
