I just got an eGo kid with 4 of the EMDCCs and I absolutely love them. I've already gone through two fill-ups on one carto, still producing tons of vapor, flavor, and TH. No burnt taste at all, hopefully that will be the case for awhile.
I just love how much juice these things hold, combined with the 900mAh batts I can just throw the assembled unit in my pocket and be gone all day and not worry about having to re-charge a battery or drip/change/re-fill carts and taking a bunch of other crap with me.
I have not tried any other cartos, so I don't have anything to compare them too, but THESE are the standard I will judge anything else I try against, and from the sounds of it, that means my standards are now pretty high.
I actually really like how the unit looks and feels, it is a bit large, as I went from a cig-sized PV to this, but it really hasn't been a problem. I just throw it in my shirt pocket when I'm driving around, or in my pants pocket when I'm walking around, and have not yet felt "man, I wish this thing was smaller" It just hasn't been an issue for me. I also think it looks better than using a regular atty and cone.
I have read a lot about the smaller, single coil, mega cartos for the ego, and I can't imagine they would be anywhere near as good as these guys. If for no other reason, filling the other cartos seems to be a huge hassle when you have to use a needle and tweezers just to fill the thing. Popping off the rubber tip couldn't be easier, although I do think I'll look into getting a mega drip tip just to try out, and see if I can fill it without removing anything at all. I'm not sure how small the ID would be on the mega DT, but I'd imagine it should be large enough to make sure the juice flows down the side of the carto instead of straight down the middle.
Because I can't leave well enough alone I really want to take one of these bad boys apart, but alas I will have to wait until one craps out. Hopefully that won't be for awhile, though. What are the main issues with these as far as wear goes? Do they just start tasting really burnt, do the coils burn out, or does their performance just continue to drop off over time to the point where you no longer want to use them?
