Okay,so i've owned this laser for about 2 years now,and i have to tell you,it is well worth it ! Especially if you have two-or four of them ! Yes,one is still amazing,but with 2 or 4,you can definitely run a fantastic DMX show,or...just master/slave them to run together....OR/ORRRR,Just sound active would be fine ! One thing to keep in mind though,is that lasers like these need proper mirror cleaning and dusting off once in a while to keep that green beam bright and "as new" because smudges on the front lense or internal mirrors can and will effect the output of the beams. It happened before where i thought the laser was burning out...NOPE ! It was just a smudge on the smaller mirror inside causing one of the reflected beams to seem really dim,but it's an easy fix !!!!!! Definitely a Must have for any DJ,mobile rig or halloween party/Haunted house. Thanks Joey and crew !
