I had the same 2 ordered. In one of them, the green laser wrong on the board (connector) Ruck Zuck housing was plugged, thanks to the 4 screws, plugged on and around. After trying several times, funtkionierte also this.
Complaint was answered by the dealer immediately. I got tips and I was still a 3 laser sent free of charge. I should keep all that I could help with troubleshooting.
