I just got my KGO delivered today, along with 2 of these EMDCC's. I wanted them due to the added capacity. I'm pretty disappointed in them actually. I thought it was going to make some kinda great vapor production along with a warmer vape, but it's pretty bleh. The mouthpiece gets warm if i hold it for 5-6 secs, and the larger volume does equal to a tad more vapor production, but the vape itself is cold and airy. They're advertised to hold 4.5-5ml of juice, but it started dripping out the bottom at a lil' over 3ml on me. I used a syringe to fill it. I cleaned it up, waited a few minutes, and topped it off thinking i may've just flooded the bottom. Nope, still started dripping out the bottom almost immediately. Thankfully i bought an 808 adapter, and i've been using my other cartridges instead. I'm waiting on my 1.7 Resurrectors to come in, hopefully they won't disappoint
