Second Look at the Surge tank

UPDATE: The Surge Tank on my GLV XL
The Picture of the surge on a Joye ego.

You can see my first look here.
I really enjoy it. I have been using ciso 306 and ikv i06 on it. They are now selling the more expensive 2 tone version at an ecig website. Here are some pics of it on my darwin.

Works great. The entender that I put to use it on the darwin stuck on to it :( Still trying to get it off. But there is amazing customer service. I highly recommend it.
