Mark,
Could you elaborate a little on the wicking problem? Quite a few of us are waiting on the 510 version to play with.
For example: Does the wicking material run throughout the liquid chamber? And does pointing the battery side of the carto down gravity feed liquid to the coil?
Be glad to... I have been following the other thread too. The wick does dip down into the chamber, and no matter how you sit the cart it just does not seem to wick fast enough. Take more than 2-3 puffs in a minute and you get the burning taste. We also got samples of the 401 and 510 models and the design is exactly the same on all of them. I have dissected quite a few, and it seems like once the wick inside scorches (which is very quickly), the burning taste is always there, unless you drip directly onto the coil.
