I don't know when they will be back in stock but I'm assuming we would also need to buy at least 4 batteries, 2 charging while other 2 in use and a battery charger for them. All in all still under 100 bucks. I don't think the boxes come with batteries. I'm probably going to wait and see what's up with the ego VV before I buy anything else.
Day two with the EMDCCs and I'm very happy with them. No problems at all. Can't speak regarding longevity or how they would run after a cleaning, but I use 70PG/30VG juice and no issues, even have one filled with 50/50 and hits great. Haven't put any real dark or thick juice in any of them yet, since I don't like any of those anyway and won't waste one of these gems on experimenting.
I had been thinking about getting the roughstack (ya, I know the EMDCC won't work with it), so I'm also undecided. I'd also like to see what happens with the EGO VV. Since I've mostly been using the atty/cart combo since I started vaping, I'm very pleased with the mega dual coil cartos and will get some 510 mega dual coil next. I was having problem with draw over the past few months, and these EMDCCs are so easy on the draw that I'm actually happy to be able to take shorter vapes and happy to be using cartos again. I've found that longer vapes on these actually make my head spin. lol That's good news for me, as I don't want to be using that much e-juice.
I thought my first EMDCC was giving out on me, but it's still going strong into day 6, and I haven't cleaned it yet. I'm definitely sold on cartomizers, now. It's nice to know I can go somewhere and not have to worry about refilling or carrying extras with me all the time. I like that these seem to be consistent. Yesterday, I did open the 2nd one, tho, to use a different flavor, and it didn't seem, to be firing as good as the first one, plus, it hesitates quite a while before firing. Not sure if this one is a dud or not. It still works ... just not as well and seems to have a harder draw. Also, I blew it out a little before I filled it, so maybe I screwed it up myself. It also seems to get much hotter than the 1st one, too. I want to try another flavor in the 3rd one, so maybe I'll have better luck with it. I still have the little plastic end caps from some regular EGO mega's (syringe fill), and they work great on these EMDCCs ... nice to have them for carrying an extra carto with me when I'm going to be gone longer ... just in case. Also, the end caps allowed me to add even more e-juice ... absorbed all of it overnight.
UPDATE: There seems to be about a 3 to 4-second delay on firing with carto #2 and it has a little harder draw, so I have to take a longer vape, but still works better than anything I'd tried before. Is it possible that I may have killed one of the coils? Or would that have killed it totally? Is this just the nature of the beast, maybe?
