Perfect fit for my vintage flashlight setup. It's getting hard to find reliable 17670s these days, but these Ultrafire ones definitely hit the mark.

The batteries perform fine and deliver stable power, but be aware of the dimensions. Because of the added protection circuit, they measure 69mm long. They were just a hair too long for the battery tube of one of my older devices. They work great, just make sure your gear has enough clearance for that extra length.
