I don't have a lot to add except this: I bought two of them, one silver and one black. I used the stock coil and supplied cotton in the silver one for a couple of days and probably ran less than 10mls through it. Flavor was nowhere near as good as the Eggrolls and CLR coils. Plus I had to run it at a lot higher wattage than I thought would be necessary. This morning after not being more than a couple of feet from my desk, it's leaking out of the air holes. Washed, back on the shelf, I'll try again one of these days when I have time. The black one's glass was nasty and not real easy to clean. The rest of the parts seemed OK.
