If you don't mind spending a little more for parts I have been real happy with my VV I worked from the evercool thread and input from several others on the forum. http://www.e-cigarette-forum.com/forum/modders-forum/191607-easy-okr-t-vv-mod.html I think all of the parts will run a little over $20
Just got the parts and finished making it. Now this mod will be my main and my current one will be back up. Thanks for the diagram and parts list. I got 2 sets just in case. In my mind its always good to have extra of everything.
