VooPoo can be both reliable and predictable. The Drag X PNP X kit is kinda just that. The 18650 isn’t amazing but isn’t awful. The PNP X heads get slurpy kinda like the TPP coil heads did. Overall the Drag X PNP X kit is a solidly “fine” kit.
Time to get rid of that top fill system though, it gets to be a much bigger pain the more you use it.
