Adam,
I haven't tried one. Maratac has a click model (or they did). I selected the AA because it is tiny (smallest AA on the market). I pocket carry a Leatherman Serac S3 (click tail cap with three brightness settings) daily. All of my other kits have Streamlight Mil Compact Sidewinders.

I am now a fictional British television police officer (currently a Detective Sgt) at Thames Valley Station. My governor is Detective Inspector Fred Thursday and it’s 1969.
