Familiarity: I've used it once or twice and have initial impressions
I just recieved this headlamp but there is NO BATTERY GAUGE, you just have toleave it charging for 3-4 hours and "hope" its fully charged. This is a HUGE defect in my opinion. You have no way to verify how much battery life is in the battery pack???? how could such a minor detail be overlooked. Even the cheapest of lithium battery products have a gauge of some sort to measure battery life. This is very disappointing.
