Front seal blew out due to tight fit with ECR holster (Sig 220 combat). Returned to factory. When I got it back, the laser dot was 3.5" ellipse at 20ft (thanks for the free pack of batteries). Disappointing to say the least. I returned it again. They sent acknowledgement that it was received on Feb 5th and I would receive an email when they ship the new replacement. Today is Feb 13 and no news. I bought this from OP in mid october and it has been in the shop most of this time. Based on my experience, a waste of time and not a good use of my money. Reference RMA 3131. Good luck if you have a problem.
Pros: cool product
Cons: poor service
