Mh, I have spend hours today researching some of the Bridgless Atomizers as the ease appealed and the sole purpose of this device was to taste my first home brewed juices. I have had an MVP 20 W and some 19 mm devices, Subtanks, nautilus and sold it all as I did not like the weight, the size or the very airy draws and was happy to vape at 10 w and below.
This is why I found it so difficult to look for just one small RDA that I can either pop onto my existing ego vv batteries (14 mm and 16.5mm) or get just one small mod. All I can find is 19 to far more mm wide or another box mod
Watching some of the YouTube reviews on the bridge-less atomizers confused me even more which reminded me what a noob I really am
