I use it for 2 years

+ Very bright
+ Nice and sharp gobo
+ Dynamic effect
+ Relatively compact
+ Good detection Music
+'s Pure plug n play
+ Mirror being protected well
+ Compact
+ One device is sufficient because it genet two beams
- No rglage
- Indeed a little faster in the large room
- Make more

tat it a bit expensive to purchase self-effect but it is justified by all these qualities.
