This thing is bright and easy to carry in my pocket and can be used as a headlamp.
OK, I'm a big fan of headlamps, so convenient and hands free. HOWEVER, this light moved right to the top of my most carried flashlight. In fact, I just ordered a second one. And, I just received a headband (Amazon) that is perfectly suited to hold this light, making it a hands free light.
The light will blind you if you get hit directly in the eyes (think flashbulb). We live on property with coyotes in our area. Taking our small dog out to do his morning business in the pitch black is routine for us. This light takes my precautionary scan around our property further than any light I have, and I've collected a lot over the decades.
I'm also a bike/backpacker and this light will go with me from now on.
I love this light. I can't speak to the life of the rechargeable battery because I haven't had to recharge it yet - I've owned it for 4 weeks and it gets used daily around our property.
BTW, I found that the Apple Airtag holders (linked below, sold on Amazon) hold the UltraFire snugly in a vertical position that can be used beside the bed or wherever (see photo). The Airtag holders have an adhesive backing. I actually have both of mine sitting vertically next to my recliner and my bed. They are very snug/secure in the holders - great for nightstands or any flat surface.
