I buy another model on an auction site known, a 400MW RGY sagit. I paid under 200 euros NEW! I was lucky.
It is not very fast (2-5 kpps) but it's a good approach. (10 DMX channels)
After 6 months, the green began to see very little work at all.
After you contact the relevant department, here is what I received in response:
The best would be to return the laser so that we can review it. We wish to inform you that in general there is no guarantee on the LEDs. If the malfunction is due to a manufacturing defect we will exchange the module without charges. Otherwise there would be the cost of repair.
So: Big distrust as a manufacturer of laser diodes do not guarantee its is a car manufacturer that does not guarantee its engines!
It goes without saying that with me, the next purchase will not happen in LASERWORLD
