I use this jewelry since about 2 months for 5-6 evening and I really think this little light effects is doing really well ....... of course we should not seek to make li form at 500 meters .. whatever ... it'll be slight .. but seeing! it consists of an on / off switch for the entire unit and another one key (two keys are delivered with) for the laser is controlled by him même.Il music, automatically, in channel dmx and another thing I think ....
In short this laser under 500mw is a limit to enter the big league! As the first laser that is a real pleasure for its owner, who does not Contans ^ PLER the number of form pre-register, and for those coming in the evening there is brief poverty reduction, small, powerful enough to be consistent and that asser fun ... plus it is very full amount

to buy (a little expensive but it has acha is worth! believe me!
