I have been using one of these flashlights for over ten years. It has been in countless tough and dirty spots (construction work), dropped many times, and it just keeps working. A problem finally developed with the power switch where it wouldn't always come on without tapping it on something, which is why I ordered another one. I actually ordered three, one for regular work use, one for around the house, and one backup. It is compact, highly durable, until recently always reliable, and it has a great beam. Even though it isn't an adjustable beam, I have never wanted to change it. I have other flashlights with adjustable beams, but none are quite as good as this one, as the adjustable beams all have some kind of "halo" effect at certain beam settings that I don't like.
I don't know if the aluminum case is a critical part of its durability, but it has lasted much longer than multiple plastic-cased flashlights that I have used. While I am not suggesting that Luxpro increase their prices, I would pay a good bit more for this flashlight. The durability is worth a lot to me.
I usually only give five stars for something exceptional, and for products (and service, for that matter) only very rarely, but this flashlight has earned it. I also love that it hasn't changed compared to the first one I bought, at least as far as I can tell I assumed that someone would try and "improve" it, but I am not sure how you could. Thankfully, no one has.

In my car console for small needs.
Great flashlight to grab and use in hurry.

Super bright and portable!! Thank you!

Lux pro is the only brand of flashlights I use. They are compact and bright
