I have 5 of their lights, two are modded so their is no tint issue there. I like 4000K to 5000K the best but deal w/ the cooler tints.
I never had an issue with any of these lights except for the S1 mini baton that I won in a GAW ,Christmas 2017. I thought it may be the driver,I was wrong. They sent me a brand new battery first, before they wanted me to send the light back. The battery was the issue.Not sure why I thought it was the driver.The point is, even though I got this light for free, they took care of me.
Anyway, they resolved the issue for that, sent me FREE cigar rings for my M2X and sent me another FREE holster. I have ZERO complaints about Olight.Although, like others I do wish they would have lights w/ warmer tints.
Lastly, I do NOT like lights with Proprietary batteries, whether it be theirs or another manufacturers. I have zero lights w/ this set up and will never buy a light that has it. I like using my own batteries and Do NOT want to depend on the manufacturer for their EXPENSIVE replacement!
