Much as I’ve been impressed with Foy’s review of the S2200’s little brother, and with the finish (for the money), of the SF lights I have, I think I’m still going to wait for the Niwalker offering.
Selfbuilt’s review on the other side of the Black Light Vostro BK-FA02 has convinced me that this is the one to get. His only criticism seems to be a narrow magnetic ring control - to me that’s an advantage after the fairly loose ring on the little RRT-01.
