Ordered it in early December, arrived last week. Finally had the time to install and function check it on my SBS Wilson/Scattergun Tech 870 this morning.

Heavier than the previous models, but lotsa nice features. I like the dual output (200 or 600 lumens) and the layout of the controls. My only complaint so far is that my hand feels a little crowded, like there's barely enough space for it. Nothing that will keep me from using it, though.
