I'm actually wondering if that is the difference actually cyborg, those that are getting on with it are running multiple PV's and those that aren't are either using just one or two. I only ever run one PV at a time, I use it all day every day, I change flavours only when I finish a tank and my consumption varies between 3 and 6 ml a day depending upon how long I spend at the computer.
The C might just not be up to that kind of work horse abuse; it would be interesting if folks could comment here about this theory because if it proves to be true, then none of us should be recommending it as a first time peice of cut and should still be pushing the T; as newbies are most likely, at least until they get the bug, to be the people who are using it in the way I do.
just thought I'd comment about the multiple PV theory....
whilst it's true that I do regularly use half a dozen PV's throughout the day in order to keep swapping flavours and avoid the dreaded "tastebud syndrome"... when I had the original eGo-C for review back in November, I used it exclusively for about 3 weeks before posting my review, so that I could give it a thorough trial with as many variations of flavour, juices, prolonged use (and yes, it does run hot when chain-vaped...)
and crucially: wanting to see how long the atty would last.
In the event, I had to post the review before the atty expired as the -C was about to hit the shelves... so it seemed important to have a review up on the boards... the atty I was using continued to perform for over 8 weeks.
I had 3 atties provided in all with the review device; the first I killed by my own abuse of the poor thing...the second went on for over 8 weeks... and the third is still performing today, although I've reverted to using a number of devices in rotation, the -C is vaped for at least a couple of hours each day as it's my favourite device for flavour etc... it goes through about 2 ml of juice every day.
My current juice mix is approximately 50/50 PG/AG and I've had no trouble such as you're describing with your atties, so I'm also thinking that the current batches of atty strips are not up to the original standard.
