The T2 is a top fed wick atomizer produced by SZ Kanger.
This atomizer comes with either short wick or long wick design. The newest design comes with a very short wick and a small rubber cup that sits under the coil to hold the liquid.
You'll notice that in one of the photos in this electronic cigarette clearomizer review that there is a very short wick - that's the new design, whereas the other photo shows the old design with a much longer wick.
Feel free to review both old and new designs below.
