Well I've only run these couple of hours now, but it's enough to say something about them. I bought 2 of these to my lightning set to be used at small clubs etc. Overall build quality is suprisingly good. Metal housing and sturdy clamp, good quality connectors and well working buttons. Looking at the price, I really cannot be to harsh on these. But some cons also, because everyone wants to know them first.
First I was unable to get any light out of these. I didn't buy the safety switch along with these, but there was a connector included. It wasn't bridged though, so if you want to test run them without a safety switches, you have to solder a bridge into the included safety switch connectors. If you don't, they will not work without the safety switches. I don't recommend using them live without safety switches but for test purposes this method seems to be ok.
Other con is the precision of the laser. For the price, its acceptable. But if you compare it to more expensive stuff, it's not that precise. It's kinda almost there. When you project a triangle, you get a triangle with some wobbly lines. But that's okay, because of the price point.
Third con is the noise level. They are loud, so if using in small quiet areas, you will definitely hear the noise.
But over all, they are very bright, they are responsive and seem to work quite well. Very well suitable for smaller clubs or events that do not require pro equipment.
