As laser I've seen better but for € 120 it's still reasonable for small budgets and it is better than the 5mw laser to € 50.
the LED is not very powerful but in a small room with a little smoky effect is nice. It is not on it rehabilitates a great party room.

For my first month by all went well, then it's off a mirror. A quick removal of glue and some gouet have been the case.

For the evening with friends in a garage or in a salon but it's still acceptable past 100m ² must be provided bigger.

Cons:
_ Build quality (recrurent to Boost)
_ Low power

Positives:
_ Simple effects and fun
_ Low price
_ Plug and Play

if it would be to redo I save a little (much).
