I own just about evey Olight made. I have never had a single issue with any of them. They are my favorite flashlight maker. I do hate the new trend towards non changeable batteries and the new switch location, I'm a tail switch kind of guy.
I put lights to hard use, I've dropped them in oil, antifreeze, trans fluid, gas, diesel and even battery acid. I literally crused one legnth wise and though I could no longer remove the battery the light still worked perfectly. That was my fault left it stuck to the bottom of a large fork lift carriage while I was replacing hoses, forgot it, lowered the carriage from 7' and crunch. Dropped them from a few inches too 60 feet high. Lost one in a freezer, 1 year and 3 days later, it was recovered by an honest worker who brought it out and asked if it was the one I lost awhile ago. I knew the date thanx to Amazon storing purchase info. Battery didn't survive, but it was low on charge also. The light still working.
So for me I will always be an Olight fan, but I'm also fan of other brands and even a few cheap lights, they all have a purpose no matter the brand. I now buy cheaper made lights for work, but I will spoil myself with a nice one every now and then. Nitecore has become a favorite work light, great pocket-sized, durable lights. Have many of those, but I'm currently trying out the baton 4 with charger case and I gotta tell ya I like it a whole lot in spite of the switch location. Just my 2 cents
