When I first got this, I was disappointed. It was bright in the house, but once I went outside during the night, it didn't light up anything in front of me. I go flying my drone before sunrise on my trike and the bike path I ride on has been a bit messy from the hurricane we had here in SW Florida. I had tried several bike lights and none of them worked for me.After charging this one, I was extremely surprised at how well it lit up everything n front of me AND off to the sides a bit. Completely even lighting across the area lit up. No banding light is what you get with some lights. No hot spot. Just smooth even light. Now, I have to say this, although it completely lights everything up in front of m, I have to charge it again once it gets to about half the battery. Now, inside, it is still very bright, which is great, but since I need a light that lights up everything every time I go out, I just simply recharge it once I notice it's changing.The light part is like the head of a nice solid LED flashlight with the glass like the lens on a camera. Kind of rounded instead of flat. That's most likely why it gives off smooth lighting. The head will go up and down about 90 degrees or so snapping into place each time you move it so it stays in place, where you want it, very well.I don't have any problem with this light. Well, one little thing is that the inside of the band in the back where the battery pack is it's starting to show some wear after only a month or so of wearing it. It uses 3 18650 batteries which don't show the mAh. It has 3 levels of brightness with strobe and SOS features. There is a button on the battery pack that turns on a steady red light or a blinking red light if you press the button again. Pressing the button also shows how much battery life you have left and there is a mini USB port for charging as well as a regular USB port if you want to use it like a battery pack to charge your phone or other devices that charge via USB.The light has a zoom feature which will let the light flood the area or zoom in on a small area in front of you. You can't tell by the picture but when zoomed all the way in, you see the 4 quadrants of the LED. The light mechanism itself is a very strong metal and seems very durable. This is a VERY good quality flashlight. Even the plastic battery casing is much better than all the others I have tested.If this one gets lost or something happens to it, I will definitely get another one. It came very quickly after ordering it. The price was very decent compared to others and then after factoring in the excellent quality, it's a very good deal for the price.I bought this myself and nobody has influenced my review. There are times when companies send me products, not the case here, and I let them know that I give my real opinion on the review of the item. I make sure they understand that. Some companies have decided not to send me items because they know they might not get a good review. I always let you know the good and the bad about my purchase. The only thing I could find, which isn't really that bad, is the wear on the band, but like I said, that's not really bad. I might ask the company for a spare headband later.Hands down, one of the best purchases of 2022.
