The flashlight is pretty good quality. It has a solid metal construction and seems rather rigid. The battery cover comes off too easily for this flashlight and I have a hard time getting it to stay on properly. I like how it comes with a rechargeable battery that you can remove and plug in. The best part about this is that it has an adapter that can be used to use 3xAAA batteries. I think that is the coolest thing as I could see using that in a dire situation like camping or traveling far from civilization.
The functions are a good selection. Honestly, I see no use for the "SOS" function because anyone who sees that light could easily hear or see you and you can see them. I think the zoomable function is neat but since it is already a bit narrow, the most use I will get out of that is if I am trying to target something in the far distance.
I am not sure if it is truly 900 lumens because it doesn't seem as bright as a 700 lumens light I got a couple months ago. Regardless, it is brighter than your average flashlight.
