I run or bike from 5-6am every morning. I used it for four days (45min on high) before it died. It’s extremely bright! Will light up around 15-20 ft ahead with no problems at all. It stays in place well, and once you figure out how to adjust the straps, very easy to use and tighten. The tilt is great to use depending on your build and to point it down when other runners are coming so you don’t blind them. Overall, absolutely love this thing so much I got an extra one. I run with my weighted vest twice a week and this way I don’t have to keep re-adjusting the straps.
Things to consider (not necessarily cons). The light has three green lights to show battery power. On the fifth day it was at two bars when I started and went to one bar shortly after my video. 15 min later, it was dead. Complete dead. I had to use my phone flashlight the rest of the run. It gave me 3 hours of solid use before that. So, I’ll just charge it once a week. I would call this a con, but honestly.. I will gladly take three hard hours of use on high being good for this little thing.
Next: it will save your last power setting. If you run using it on high power, then lower it to low once the sun comes up. Then you turn it on the next day. It will come back on to low. It will not default back to high. So if your light looks dim, cycle back to high.
Overall, I highly recommend this. Test it out and see how many hours it gives you. Then decide when you need to charge it. I can complain about the three bars inaccuracy, but it works and it works well. So no complaints from me.

This was the perfect investment for my 5 year old to wear on our morning walks. It fits him with room to grow which is nice and the durability seems to be strong. It’s very bright for the light part and I would say the reflection is the perfect amount as well. He says he think it’s comfortable and doesn’t complain about it being to itchy which is a huge thing for him.

Will be too big if you're very petite: I'm 5'4" and 120 lbs, and even with the straps tightened to the maximum shortest, it's still right on the edge of being too big. I can still run with it and it stays in place, but for a person smaller than me it won't work. I'm thinking of hand-sewing the straps shorter so it's more secure.
Also, if you find the chest strap is lopsided – move the circle in the back, it's movable along the strap.
Other than that, I have no complaints about the light itself – it's powerful and there's 3 intensity levels for white and it even has a red lamp. Great for running or hiking in the dark.

My husband and use when we walk very early or late evening. Allows us to be hands free if we have the dog with us and totally visable to on coming traffic.

Wonderful addition to my running gear. I used it for a night race and I use it when it is still dark in the morning for my runs. Very effective. And when I don't need the light it has the reflectors so I can be seen.

Got two of these for my kids because they hike and walk in the dark. They love them. The light is bright enough to illuminate the path and the uneven trails they walk on. They find them comfortable to wear and easy to put on and take off. Light weight, durable and easily stored in a small space.

I typically don't take the time to write reviews but I had to let everyone know, if you need a light for jogging or walking in the dark, you should strongly consider this light.
I've tried several lights as I do a lot of jogging in the dark. This is my absolute favorite light BY FAR! It's super adjustable, very bright, and lightweight. I'm not a fan of lights that you wear on your head because during the warmer months, bugs will be attracted to the light and fly right in your face. Yuk! However, since this light is positioned at chest level, that issue is diminished greatly. Yay!
So, for all my fellow night or early morning joggers who are looking for a light to use while jogging, you should give this light a try. I hope you love it as much as I do! ❤️
