I ordered a bunch of rare earth magnets about the size of the button on button-top
batteries that we use on our flat top
batteries for Grands and Minis. For us "old timers" just a little help with button action goes a long way.
For my old Woody I use two very thin larger diameter magnets that help it to fire better with the flat top batteries. I don't know why it helps but it does help.
I had to search a bit to get just the right size rare earth magnets. Most e-cig suppliers, if they even have them..... they are larger than the buttons on button top batteries.
I have some AW HD batteries coming in that have button tops, but in the mean time, my flat top HD BDLs are not that old so we have to use them.
