I just got the ones from MadVapes today. I got the clear ones, and I would recommend it because you can actually tell when all of the filler has juice in it. I noticed that it's rather difficult to get all of the filler with juice. Would probably be easier with a syringe of some kind with a long needle.
So far they are producing tons of vapor, and I'm using a eGo battery (even though they don't recommend it).
