About two weeks ago, I knocked over my rifle, and the 12:00 mounted Surefire X300 absorbed the brunt of the impact. The impact broke one of the screws that holds the rail guide to the body of the light leaving half the screw in the body of the light and the other half in the rail guide. No big deal, I'll call up Surefire, get an RMA, and have my light back good as new in a couple weeks.
Fast forward to this evening... I got off work and was happy to see a box with a Fountain Valley, CA return address waiting for me on my porch. I open the box expecting my old X300 back in working order and a Surefire decal, and instead find a BRAND NEW X300 Ultra !
Surefure replaced my purchased second hand, who knows how old, trivial to repair, damaged through carelessness weapon light, with a brand new one...no questions asked.
I have had good experiences with Surefire CS before, but this absolutely takes the cake.
