Hi Caged, The Did style atties have a reservoir tank that feeds the wick. In this case the wick is stainless steel mesh. The wick feeds through the coil which is wound around the upper portion of the ss wick. Here is a pic from GP
DID style DIY TANK atomizer system There are many tutorials on how these can be setup and it would be good to know a few of the ways that these could benefit your personal vaping style. I do not own one yet but I am going to now that Rob carries them,on my next order. I have been eyeing this exact piece but I only order from GP since he has been such a great vendor throughout my personal vaping journey.
The Vivi on the other hand is a big ce2(4?+?) with a removeable head that can be replaced inexpensively. You just unscrew the old head and screw on the new one. They are super easy to clean and keep maintained. I do own one and can say that I have retired almost all my other atties/cartos and devices in favor of the ease of use and their overall rugged quality. If you do order one I would also recommend the optional metal tubes that are available. They(metal tanks) dont break, they dont leak, they dont react with the known acidic or cinnamon liquids. I pocket my device with the vivi attached, and have never had a single issue, in almost four months. One more thing I have found with the vivi tanks, I have noticed the silicone sleeve that comes inside the drip tip that is included with the vivi works very well to keep the inner silicone and cup placed center and sealed. You just need to assemble the tank then before you put the drip tip in slide the retainer( drip tip sleeve) down through the hole in the cap and this will keep everything straight and lined up like it should be. Good Luck. Happy Vaping.
