I've been using the Vision eGo Clearomizer for a few months, and I was very happy with it. It's a well-made piece of kit, and looks great on top of a large eGo battery. Unfortunately the latest batch is a new version with longer wicks, they do seem to have developed a major leakage problem. Liquid is getting into the centre tube and leaking down onto the battery connection and into the air inlets at the bottom. I just bought three new ones; one was DOA and the other two leak so badly as to be pretty much unusable. As far as I can tell the problem lies in the new wick. It seems to be thinner than the old shorter wick, and allows liquid to leak into the centre tube. I've tried pushing the latex cap down with the tip of a screwdriver but it hasn't helped. This is very disappointing, since it's ruined what was arguably the best clearomiser on the market. I hope the manufacturers can solve this problem, because until they do I will not be using them.
