I don’t really like the input lag on the switch which is unusual for a “tactical” light

Which input lag do you mean? When it press the switch, my light turns on immediately.

Don't compare the flashlights you'll find here in c/flashlight with these cheap flashlights with fake lumen ratings. 😉

Huh? That never happened with any of my flashlights. Mechanical tail switches are pretty reliable.

It performs OK, a little hard to press completely, though. Momentary mode works great, but it requires some force to press the switch completely. Apart from that it is reliable and relatively pocket-safe.

Practicality depends on your preference. It's heavy, some people say it stinks. But scratches don't make it look ugly and it ages nicely with time.
