I’ll start off the pros: lots of light level options and features; ability to turn light up and down, USB-C charging with great battery life. I’ve gone 2-3 weeks without charging it but I was using the lowest light setting. The brightest light setting is comparable to the Milwaukee’s. The light head itself is a little big but it’s light. I also use it with a hard hat so I can say I experienced any discomfort but the straps were nice and they were adjustable. Overall easy to use as there were some videos online. Basically set by clicking the button or holding. Main concern is that the charging port cover is hard to put back in and I’m not sure about weather proofness

Overall great headlamp so far. I have been using it for working on cars and being able to cycle between low, medium and high is really useful. The built in charging works well, but it is also nice being able to remove the battery and swap it out. The light is super bright, it has a hotspot in the middle which is good for seeing far away, but it is also foody which helps brighten up things up close. The light is plenty bright for reaching the tops of trees far away or looking at the ground close up/lighting up the underside of a vehicle. By far my favorite headlamp so far. *Cliff Notes* Charging: Charging works really well it uses a USB-C port or you can switch out the battery for another 18650 for a quick battery swap. Brightness: 2000 Lumens is really bright, and it also allows you to cycle down to low and medium when you don't need full brightness. The light has a throwy hotspot which makes it useful for far away, but it also has a floody glow that makes it useful up close. Overall great for night hikes, biking, and working on cars. Conclusion: Much brighter than store brand lights with great run time perfect for a headlamp or a right angle flashlight. UI is simple enough anyone can use it. Would make a great gift for anyone.

Great brightness options, battery life great. When wearing, it stays at the angle you point it, yet easy to change angle. I personally don't like the charging port exposed to the elements, but the rubber plug hasn't allowed any water or dirt behind it, yet. I keep one on the drivers headrest, super handy and out of the way. At the gas station I used it and for convenients I stuck the magnetic end on the Jeep while finishing to refuel and get a drink. At the end of the on ramp for the interstate (traveling 70 mph) I hear a strange clunk and quickly realize it's the light, I observe it bouncing down the highway in my side mirror. Afraid someone would run over it, I hike back to retrieve it. It's scratched and nicked pretty bad. The lens is unbroken and it still works flawlessly to this day ... this treatment not recommended for your light!

If I can give this zero starts I would ! I got this flashlight for my son for Christmas and he absolutely loves it! It’s nice and bright when he goes outdoor hikes! Although the price doubled in the past 3 months I figured I’d get one for myself! I’ve returned this product twice it will not turn on ! Are you sending me duds! $40 dollars for a product that does not turn on.

It definitely does its job. It's a little on the heavy side, and that was a factor last week when I did a 6 day, wilderness pack boat trip. I wish the detach/reattach/adjustment system was a little nicer. It's just strong, rubber webbing that you have to slide over the cylindrical shaped light. It's very tight so attaching and roving aren't all that fast and easy. When you twist it to aim higher or lower it tends to grip the rubber and twist it rather than just moving within z if that makes sense. Minor issues really. It's a great light. I'd buy againoat likely.
