I have a Zenesis mini, which I purchased (at a premium price) from the classifieds. I also have an Odysseus running on a Provari. Both the Genesis style and the Ody with non-resistance/resistance wire coil are much easier to setup than you would think. They are very different, the Ody is a stiffer hotter vape which I find more satisfying while working all day, mostly because it is sturdier, with no glass
tank, not to mention it DOES NOT LEAK EVER. PERIOD. (yes I know that was multiple periods). The Zenesis is much more satisfying when I'm relaxing at home. Kinda a cigarette vs pipe type of thing, the Zenesis makes big clouds of cooler more flavorful vapor, but doesn't have the punch of the Ody. Having tried both, I could not give up either one. They are not hard to build and maintain. My first coil on each worked fine, but each coil I build performs better and lasts longer than the previous one. I recommend either, I highly recommend both. All my other
mods, and I have A LOT are sitting in a cabinet cleaned and unused. I'm about to start giving them away to my friends, because I just don't see myself ever buying an atomizer or cartomizer ever again. Go rebuildable, you won't regret it.
P.S. - Here's the videos that taught me what I needed to get started:
Odysseus:
REVIEW OF THE ODYSSEUS REPAIRABLE ATOMISER - YouTube
Zenesis:
zenesis coil basics - YouTube
The Zenesis video will also apply for Katanas, Orions, and other Genesis mods. The layout may be slightly different, but the basics are the same.
If it seems complicated or overwhelming, trust me it is not. Once you try it yourself you'll be suprised how quickly you catch on.
Good Luck, PM me if you need any help.
