We just released another new product on the site. These KR808D Dual Coil Tanks. We have a couple different varieties available now. We have 3.5ml Tanks with plastic end caps, 6ml Tanks with plastic end caps, and 6ml Tanks with Metal end caps. All have the same 1.5Ohm resistance Dual Coil Cartomizer inside. These carts have been specifically modified by Vapor4Life to have 2 holes in the cartomizers so that juice absorbs better into the internal carto. They also come with 2 drip tips each (a soft rubber, and a hard plastic).
I have been using these for several days and I really like them. The 6ml tank, I can fill up in the morning and vape all day. I also have not had any problems with leakage on these. They work great on any of our Vapor4Life batteries, the VGO, or the 5V OMG. I was actually very pleasantly surprised how well they work on the new Manual Diamond Series batteries.
