Hello friends. While I wait for the seller to respond to my question, I thought I would see if you guys happen to know. This flashlight works just like the CooYoo and Mecarmy lights. Twist a little for low, twist all the way for high. Problem is, mine inconsistently goes to high. I haven’t dropped it, or knocked anything loose. I suspect the problem is that foam padding around the contact point. At first it was touching it, but then I spread it off to the sides so it’s not touching (I will post pictures soon). Does that foam touching have anything to do with it at all? I assume it’s some sort of insulation, maybe adding resistance to the circuit that won’t allow it to ramp to high, but stay at low at all times.
Please be aware, I am no circuitry guru as you might have read my jumbled description above
