Works good. A little bulkier than most tape switches. *Call and verify operation with your lite* AER-04 did not function as intended. Had to order AER-05

the main issue I had with it was twisting it on and off the light to change the battery. Once zip tied to the rail the wire couldn't twist enough to remove. I have to loosen the light mount and twist the whole light with the tail cap stationary. Buttons fill great. No noise on the momentary and i love that there is actually a m-lok mounting option.

The part that screws to the flashlight is well made. The wire that is integrated into that part is a bit frustrating. It adds too much length. It would be nice if this could have a right-angle to it, or, better yet, be plug-in so that a person could choose right angle or straight (like with a 3.5mm connector or other barrel connector). The switch is overly bulky. Again, if it had a plug-in connector, a person could address some ergonomics. But as it is, it's decent, effective, and seemingly rugged but leaves a bit to be desired.

Nice

Received with HT18 flashlights as a promotion. Thanks again
