The one on the left is a le petit gros. The middle one, I need more detailed photos of. The one on the right looks like an mcr.
The switches and buttons in the bottom look like mcr parts.

Dibs on the le petit gros!

They got delivered a while ago now, correct the one on the left is a Vaponaute le petit gross, the other two are MCR with magnet switches.
Still not used the le petit or the small MCR not got any 18350 batterys, for the le petit i need a 22mm attie with airflow higher up as the 510 adjustment plate is recessed.
