I have a lot of vapes and there are a lot of 510 threaded batteries and cartridges but the Palm and the cartridges that CCell makes are just the bomb!
They hit shatter than almost any pen I have used as well as they are easy to fill and with some wax liquidizer you are literally set forever!!! You would be able to fill your own cartridges and then hit them anywhere you go because the palm is so small ti will fit in anyones palm!
There are no buttons just plug and play, the only thing you do is screw this magnetic piece on the bottom of any cartridge you are using and thats how it stays in the palm. I really like this feature along w the size because it feels good not only in your hand but in your pocket as well.
