I should clarify my previous post by saying I’ve never used an eraser on any of my vapes. Not that it’s bad but I never have, and I use Blu-Tac for the battery door and light ISO (before Blu-Tac); light ISO on a qtip for the bottom contact - without disassembling the TM. I would not recommend taking it apart just to clean the bottom contact.
I have taken my TM apart several times for various reasons. Most recently last year to sand it down and apply a few coats of beeswax. Prior to that it was to fix things, some of my own volition and some not. Additionally there is the sight loosening of the main screw to correct the power loss and perhaps burnish the points as
@clive_bob puts it well above. I don’t know the exact reason or what to call it but that sounds spot on. This I’ve done a few times too over 2.5 years and it corrected itself each time. And voila, the TM again rocks. I LOVE this vape!
I’m getting the RED one
It could be plywood for all I care, and I know it’s not - and I’m getting the RED one
