I have had a few head torches where to be honest they are all much of a muchness where this falls into average categorythe redeeming feature is the light body is made from a lightweight alloythe driver for the led can fun hot where i have had the lamp body fall apart due to the plastic body distorting due to heatthe adjustable focus is a nice feature normally only found on single lamp unitsthere are some comments questioning the luminaries of the main beam one has to be aware this marketed as a head torch so one shouldn’t expect a searchlight beam situationi did see some comments regarding the head band getting uncomfortable where the trick is to adjust the elastic straps so they hold the unit in place but not excessively tightregarding the waterproof comments i wouldn’t suggest suitable for subaqua work but caught in the rain is not going to affect itwoul
