The modular illustration in both OP and the BG page shows the tail cap separated as normal (?). Strange. I had one ordered as it was a great deal with Fin’s coupon (was considering it as a backup to my current micro nm1), but got refunded due to none in stock. Maybe just as well, couldn’t deal with a fixed tail cap. All my e-switch lights get the “twist” when offline, and I don’t like doing it from the head end unless necessary (ie; FWAA).
