I have roughly a dozen or so different Emisar flashlights. Fit, finish and firmware are awesome on these guys. You can really nerd out selecting specific LEDs and tints.

This has been collecting some dust in the garage for years now since I haul the bike around in a truck these days. In great shape, very little use, no rust. Fits a 2" hitch, bolts down tight and does not rattle.
