Keep out of mist/drizzle - Crimson Trace CMR-201 Rail Master Red Laser Sight w/ Universal Mount

First and foremost, thank you crimson Trace for your excellent customer service and for replacing my sight after sending it back.
I was happy with this sight, and own two of them. Never had an issue and they are a good deal for the money. However, I went out hunting this fall, and there was a light drizzle/mist at one point off and on for about an hour. This was the first time I brought that gun out hunting and forgot the sight was on it before I set out.
The sight didn't work there after. Wish the manual or online resources had a water resistance rating. Customer service was awesome though and replaced the sight asap
