Here's a really long story. . .
I tried the EgoT, total bust. Dry hits caused both the atomizers to pop within days of purchase. Tried it with a 510 atomizer, discovered dripping is NOT for me. Tried it with Smoktech cartomizers, got one too high/low [2.2 is too high?] in ohms, and fried my battery the first day. Tried the correct ohm carto in a tank, flooded constantly and leaked.
Bought a Boge Leo from a friend who just could not take to vaping, it also had a tank but never a dry hit and never popped the atty. Bought the Boge XL Cartomizers and found my perfect setup. Good flavor, high capacity carto, but they also flooded quickly and lost flavor rapidly. Back then it was about $5 for one. . .
When I picked up vaping again I bought some Leo clearomizers. Good flavor, taste less like filler material, but they also leak and break apart from their bases resulting in spillage all over the inside of my purse. Used my same Leo battery. Now, Boge/Innokin has changed the Leo/Lea connection to be more 510-ish. It becomes next to impossible to find my carto/clearo in stock anywhere that will fit.
Long story short, went back to ego threaded batteries, bought 2 clearo's that people are talking about right now. Evod and Kanger T3. They are great so far, just using them a few days. No leaking, no gurgling, no dry hits, really good flavor [not polyfill] sounds less like sucking air through a straw, not tight enough that you feel like you're drinking a milkshake through a coffee stirrer.
Also got a variable voltage mod on the way, want to see what all they hype is about [plus it is a thing of beauty] so we'll see how that goes. . .
I don't remember from your original post, but had you already tried clearomizers? The rebuildable ones seem like they are going to do the job for me that nothing else could.
