please, stay away from that polyfill stuff, super nasty! if you absolutely have to use an atomizer with a polyfill cartridge tip, at least do the pyramid teabag mod thats on u tube. Ive already been through tests of using a drip tip on my bridgeless atty's and the only real problem i get is that the liquid mix of DMT and e-juice doesnt like to come out of the bottle to easy.
Don't worry abot the CE3's leaking, they wont so long as you follow the fill directions and when you're done using it gotta put the bottom cap back on.
oh yeah, the only difference between a bridgeless atty and a regular 510 atty, is the metal mesh hump thats inside is gone so you can drip directly onto the coil.
Also, I personally think that its gonna be real hard to burn DMT in a personal vaporizer.
I dripped straight spice right onto a 1.5ohm bridgeless atty on a 4volt device and had an exceptionaly large and smooth hit, no coughing, no broken glass on you're tongue taste either. food for thought
