I use it near depusi 3 months it is too little to judge him but he turns 25 figure impeccable good effect in Stoke soon becomes repetitive but its good for 130euros what more, the green laser is well 40mW (tested) and 30mW not like the dealer may say, if not for a party of about 300 to 400 people but this is more than enough good looking does not impact worthy of a great laser show of style ... ect Cap'tain this laser makes beautiful little effect and it is very nice for 130euros is one of the best product at that price, Value / Price nothing to say if it did quond value for money! our 8 / 10 the ventilation has some noise
