Just got a new SF M1 IR illuminator; comes with the standard clickie. However, this one just doesn't work right, right out of the package. Occasionally will click several times in a row, then won't click at all unless I move my thumb around and find a place it will click. I've not seen this on any of my other SF's. I bought it on Ebay, sealed in plastic with O rings, lanyard, and got a great deal. This was clearly sealed and never used, looks like it was military issue. Should I return the clickie? Will they take it?
