Very small 40W mod with built-in 2300 mAh battery, VW, VV, first version with top adjust buttons has no tc. All Presa have a slide lock for the fire bar, very pocket-friendly.
Good feel in the hand, good 510, pretty good but small display. I've used it with Smok Baby Beast .6 coil and Tobeco Super Tank Mini .2 coil, both at 35W and it hits pretty good with both. Both these 22mm tanks have no side overhang and sit with less than 1mm gap above mod. Micro USB charge-only port is low on the back so it can sit upright or vape pass-thru while charging.
Ideal use would proby be with a high ohm MTL tank that could vape a long time on the limited battery power.
