FETIN Cree Q2-WC 3-mode 150-Lumen Memory LED Flashlight (1*AA/1*14500) from KD

Anyone had a look/have/played/destroyed this light?

I was looking through my bookmarks and found this from a while back. Seems to have customisable modes??? but typical of KD, there is barely any information.

Looks Neat, has what appears to be a selectable non-disco option, and tailstandable design, and is 14500 compatible.
