An OK lamp. Took a full week to leave the seller. Had to add some foam to the back of the battery compartment using hot glue, to make it tolerable to wear for anything longer than just a couple of minutes. It's simply too uncomfortable as it comes. A small oversight/corner cutting which has a hugely negative impact on the usage of the product, so for this I will deduct one star. As for the light itself, it fits the role it was intended for perfectly. Hours and hours of operating time on full brightness, so long as you make sure to get a pair of high quality 18650s. The dim little light on the back of the battery compartment lights up red when the lamp is on, as well as serves as a charging indicator: red while charging and green when fully charged.
very bright, light can get accidentally turned on
