I understand that certain police departments use Pelican flashlights. So I am assuming that it should at least be very durable and reliable and should last quite a long time. . other than that it is not the brightest flashlight I have ever owned. I collect flashlights and have quite a few of them. Many of them $50-$200. This one was $70. It has enough lumens for doing inspections and searching for things nearby but does not throw very far at all. It does have the zoom in and out feature and also uses a 18650 rechargeable lithium battery which is common in a lot of the more expensive flashlights and you can recharge the battery in the flashlight. But besides not being very powerful it's also on the large side for a flashlight that only puts out 300 lm. I bought a Fenix that has the zoom in/ out feature as well for a little bit more money but it is smaller and also puts out 900lm. Far more brighter than the Pelican. But the FENIX cannot recharge the battery inside of it but I don't typically charge my batteries inside the flashlights anyways, so to me this wasn't a negative thing about the FENIX. So the Pelican has some good points definitely. I was deciding whether or not to return it but I will end up keeping it because if police departments rely on this manufacture, then I should at least expect longevity from it and will use this one as one of my ''beat up'' flashlights for service work that I do on automatic pedestrian doors.
