Yeah, yeah, yeah. Well over 1,000 rounds through my gun and over 500 through my wife's, the CT has never failed us. Batteries? Change them once a year for free from Crimson trace and your good to go. BIL has over 500 rnds through his SR9c with CT and never an issue.
The CT is the only one I think makes sense. Any others with a button you have to be sure to push other than with a normal grip, isn't worth it.
YMMV.
Apparently you haven't met our friend Murphy yet...
