Battery is super unpredictable. Sometimes it lasts the full 3-4 hours, sometimes it only lasts 1 hour even with a full charge. When its fully charged, its really bright but it gets noticeably dimmer as time goes on. It seems to put up with water okay, but I havent been in a ton of watery situations. When it works, the light is bright and clear, but again it gets dimmer as the battery drains. If you are looking to actually do work in dark places/at night for long periods of time, do not rely on this.

What a light! Living in a rural area it’s nice to have such a bright light to use when you out with the animals. It’s comfortable and charging is easy. Would recommend to everyone

This headlamp is adjustable but well fitting, as well as lightweight. It provides bright light, in both solid and strobe light patterns and alternating clear and red colors. It's perfect for working or performing any activity in low light conditions and the fact it's rechargeable is also an enormous plus. Would definitely recommend this product.

This headlight has alot more light than I thought it would. It stays in place great and I love that it's rechargeable. The one thing I would like to see different is I wish you could turn the rear lights off.
