To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I love these retractable head lamps. They're lightweight and compact and easy to throw in a pocket or a day pack. Very convenient. I've owned several over the years and always go right out and buy a new one when mine breaks or wears out. They now turn on at the lowest/dimmest setting which is nice. The little glow in the dark ring around the lamp is a nice idea and makes it easier to find in the dark, but I'd kind of prefer that when I turn off the lamp all light is extinguished. I'm knocking off one star because they now appear less well made; the plastic on my new one is definitely thinner and flimsier than previous models. Time will tell on how well it holds up.
OK. So they don't advertise it as waterproof. But I make the assumption that outdoor gear will just be waterproof. I left my last one in the dinghy (salt water environment) and it was toast in a few days. It just couldn't handle the exposure to salt water. So then I got a replacement because I love the design so much. Lost a star because of how quick the salt water killed it.
