I finally tried out the C-E2 clearomizers and figured I share that experience (despite there being that many posts about them already), because I got a little annoyed and went overboard:
I tried the 510 standard @2.8-3.0ohm and the 510 XL's @2.4-2.6ohm with my trusted-for-any-voltage-and-ohms Honey Flue Cured e-liquid from Liquidxpress. I used the XL on the eGo, the standard on a 510 Mega.
First impression (after filling, priming the wick, doing a few non-inhaled puffs): "I'm better of sucking in the fumes from a car exhaust". The taste was nasty - the flavor seemed burnt to beyond recognition.
And this is the "improved" version?! You've got to be kidding me!
Rather then just have the clearomizers sit around to collect dust, I decided to sacrifice a couple to see what the heck is causing that awful taste, since there are so many different opinions being posted about possible causes.
I took two clearomizers apart. There was, just as I had expected, some visible tiny fluid droplets located inside the clearomizer. The fluid turned out to be water! The water evaporated at room temperature and I got my first closer look:

I moved in closer and noticed a sort of wet sheen on the wires:

To really get a better idea of the substance on the wires, I used the microscope to zoom in:

I used an inoculating needle to transfer some of the sticky stuff from the wires to a piece of paper.
Much to my surprise the substance was water soluble, so I kept looking around and found this:

The little red spot marked by the green arrow is located in a cracked solder spot. The red substance is water soluble soldering flux. As mentioned before: There was moisture in the clearomizer. I'm assuming that the clearomizers are in fact being cleaned by the manufacturer. However, that cleaning doesn't seem thorough enough to get rid of the flux (rather, it distributes the flux evenly over the entire inside assembly of the clearomizer).
BTW, sorry about the bad pic quality. I used my webcam to take the shots at the microscope.
Anyways, I'm now happily vaping with a clearomizer: It got washed in hot water with Dawn, boiled for 15 minutes and spent a few hours in Everclear, got rinsed again and ... wow, Honey Flue Cured tastes like ... yupp, Honey Flue Cured!
Short note: I cut the inner seal wider at the notches and cut a little V on the opposite sides on the inside (can't remember where I read up on that). I did not reinstall the secondary seal. That way the wick doesn't dry out (there's no waiting in between taking puffs and so far it isn't leaking no matter what position the clearomizer is in (up, down or laying sideways). Hats off to whoever came up with that idea!
