Hello ECF, Just a quick look at the Davide BDC Glassomizer from Anyvape with the Aspire BDC heads. What's BDC you ask... Bottom Dual Coil You may have seen pbusardo's review on the Aspire heads in some other style tanks. As far as I know this was the first BDC glassomizer. I got mine in the mail yesterday from Gotvapes. Took 8 days First Class International (R) from U.S. to Canada and arrived in perfect condition, as always from them. (Seems a little soon to review but was just so impressed I couldn't wait) Workmanship Amazing, It's got an excellent weight to it, Nice buttery threads and a Smooth finish. No leaking/flooding or burning so far. holds about 3ml of juice. Flavor I'm really amazed with the flavor from these, far beyond my expectations. Throat Hit Really solid throat hit, (might need to reduce my nic) was a little strong at first. Vapor Tons of vapor Conclusion My favorite bottom glassomizer yet, They defiantly stepped up the game on this one, I really can't find a bad thing to say about these (Yet), The vape quality is considerably better in flavor, throat hit and vapor than the single bottom coil glassomizers I already own. Verdict For about $22.00, if you're in the market for a glassomizer with intense flavor this could be the one for you. (Kangertech also recently produced a BDC placing it in the new Protank 3, Hope to see or hear a review on these soon) FYI The Davide BDC set up also fits on the first two Protank models with no issues. And the Davide BDC can still use the single coil Kanger style heads. So now for a quick follow up. Let me start by adding some info, that I forgot The kit came in a small paper box w/ a formed plastic insert, containing the normal flared beauty ring and also 2 heads, 1.8ohm and 2.1ohm. The 1.8 ohm head has 4 little holes in the side of the head, and the 2.1 ohm head has 2 holes. The 2.1ohm tested at 2.2ohm and the 1.8ohm head tested at 1.9ohm That being said, Lets cover some flaws. I based my opening review on the 1.8ohm head with 4 holes, I vape 100% vg Juice and set my voltage to taste at 2.0 volts. This head performed without issue. But, when I changed to the 2.1ohm head with only 2 holes, this is where I ran into issues. Because this head only has 2 holes it failed to wick properly with the viscosity of my juice and I ran into some dry hits. In fact alot of them. I fiddled a bit with airflow to create vacuum and it did ok for a while, but still got a dry hit now and then if I chain vaped it. So for me with my juice viscosity the 2 hole design just doesn't perform well. This next issue really isn't so much a fault on the unit, but I feel I need to add it anyway. Most of my review was done using my Provari. I did however try it on a couple of my freshly charged Joytech ego-CTwists and was not impressed. The dual coils just didn't seem to get the constant voltage they needed to work properly on these. Flavor was still intense, but throat hit and vapor was really diminished on the Twists. Well that's all I really got for now on this. I still hold true to my opinions in all former statements on quality and performance. I really do like this Item. Thanks Guys and Vape On!!!
