oh goody, I should be getting my 18650 e-power tomorrow as well. I guess that is the one you are saying has the button problems!!!
The good news oly is that regardless of which E-Power you got, the switch is easily replaceable. And you might not even have an issue with yours.
And you have to remember ... for each unit sold that someone registers a complaint about here on ECF there are probably many, many hundreds sold to satisfied customers that we rarely hear anything from.
