There's also this thread, which has been going for a while: https://budgetlightforum.com/t/-/2944
I won't be able to test mine until tomorrow. I literally don't have any 18650 cells at the moment because I loaned them out and the new cells I have on order haven't arrived! Manafont decided to take its sweet time for this order!!! 
But I'm also gonna get some XTAR batteries with the charger. It's been bugging me having this light for the past week and not being able to test it. Although I did throw a couple CR123's in it for giggles but they're old cells.
