Flashlight recommendation

How important is user interface? You haven’t mentioned anything on the subject. Some people absolutely hate having to cycle through blinky modes and do not want to replace driver or firmware, others don’t mind or even like blinkies.

Another light you might want to look at is the Convoy S9. I don’t have one yet (they are on the way) but appears to be a nice light with micro USB charging port. Convoy S9
