Common complaints
Not designed for everyday carry due to size and weight.Turbo mode runtime is very short (50 seconds at max output).Higher brightness levels have limited runtime due to heat management.
Large size requiring two hands to operateNo full-length knurling on the tube for gripRequires button top batteries; flat top incompatibleSome dust found inside reflector in samplesSpot beam very tight, which may not be preferred by all users
