I too got the MFS version of the C last week. Hate to say it, but they have been horrible. Worse taste I've ever got from a ecig, period. First, it would barely work. Then thanks to another member on the model specific forum, he informed me about having to lower the inner wick, which I did and it worked better. I wasn't getting dry hits and burning wick as before, but there was not a lot of vapor production for a decent throat hit. I've tried living with this and been through at least three tanks, swapped out for new atty's, but that taste is still there. Called MFS and didn't get a clear answer. I was doing everything right, but it just wasn't working like I thought it would. This tank system can't even compare to a regular type A ego model. I was really disappointed to say the least. But, I don't know if it's the actual design of the C system itself or if it's strictly the MFS version. Do I want to spend an extra 25 bucks and get a blister pack of the Joye Ego-C's to see if there is a difference? No, not really. Already wasted enough money chasing. Before any passes doubt on my end, let me tell you what all I did. I normally use VG, didn't work, so I switched to a PG juice, no difference. Thinking was that VG was too thick to pass through the wick at an acceptible rate for vaping. Blew out all the atty's before placing them in service and went through 3 tanks before reaching this conclusion on the taste. I know about the potential of primer fluid in there, but after three tanks, that shouldn't be an issue. I've twisted the tanks themselves at least 90 degrees, and then read on another post, to try to spin them 360. Did that, no difference. I actually tore about one of the atty's and saw that it was burning the wick material because of the dry hits. Great, I've been sucking up God knows what trying to get this thing to work. After pushing down the wick from inside the drip tube, I could finally hear the juice sizzeling on the atty all the time and not for a second or two, but vapor production was minimal. I tried covering the side air inlets on the base to see if more vapor would be produced, nothing. I've played with adjusting the incoming air into the atty, no difference. Battery works fine, so far, but I did get a weird 5 blue light flash one night on one of them that I had just charged and it quit working. I recharged it and so far, knock on wood, it seems to be working. What I didn't know was that when I saw the Ego C for that price, it was not an actual Joye brand, but the MFS. I simply didn't know and, like the rest of you, thought that price was great. Now I know why. I probably should have waited for the actual Joye brand and based on what I've been reading, most members that have the Joye brand simply love it. I would love to try it, but I'm tired of wasting money. Now, don't get me wrong, I've ordered a lot of stuff from these guys in the past and have nothing but good to say about them. Love the Kool VG liquid and that new free sample of methol or mint gum is really good. Would definently order some of that for next shipment. But this MFS version of the C has been very disappointing. Looks like I'm just going to have to stay with the Ego A model and carry around extra juice and/or prefilled tips.
