What's the appeal of Mechanical mod's and Dripper's????? I've got them, and don't think much of them. I much prefer my VW devices and tank systems (kayfun/Taifun/Aqua). I use one of 2 devices daily either a DNA20 Futura or my Semovar (15w) and think they are a much better option...
Even when I've built drippers in the .7 and .8 range (as low as my DNA20 will fire) comparing the vape from that dripper in a Nemesis with a VTC5 battery vs my DNA20, I personally think the vape is stronger, thicker from the DNA20...
The only real appeal I see to the Mech's is price, and then only the clones. The genuine stuff (while worth every penny I'm sure) is just as much as a high end VW device.
Obviously I'm missing something, just curious what it is. ????
The short answer is, "Because you can do anything to your hearts desire!"
~And that's the other major selling point to us mechanical drippers, we're all DIY (tinkery) types of people, who like to be unrestricted, and basically control our own vape the way WE design it, not the manufacturer. If you don't like dripping on a mechanical, it's simply your fault for not building it right, with the right RDA with the same chamber as your kayfun, you can make it vape identically, better, or more mellow, YOU control your own vape basically. I personally love the idea of the GI2 VV/VW because it can do a max of 168 watts down to I think .2ohms, now THAT's a VV/VW that I can deal with. But it looks like an 80's cell-phone sooo.
If you've never tried a really low ohm coil (around .3 ohms at least, dual coil especially for me), then you honestly don't know what your missing out on. Take an instantly hot sub-ohm setup, add proper airflow to turn that heat into vapor, combine it with the superior wicking speed of RDA's (and remove the "safety" limitation from you VV/VW device), and finally add your favorite juice, I guarantee it'll blow your mind. Unless you don't like instant, billowing clouds of flavorful vapor of course. If you like a smaller amount of vapor, and waiting for you juice to wick in exchange for not having to put some drops in every now and then and the same/similar amount of flavor from an RDA, then RDA's definitely aren't for you. But with a tiny amount of effort and knowhow, you have much more versatility, and capability to achieve your vapors utopia.
I really don't think your futura is being used to it's full potential, I bet you don't go above 13 watts that often, personally my vamo v5 was enough for my russian 91%, any more and I'd be vaping cotton. (I like to chain vape pretty hard though.) I do understand the convenience of RBA's I really do, and the kayfun (off topic) straight up looks good as a topper, but trust me I'm so accustomed to the hearty mechanical/dripper vapor lifestyle now, that I can drip while I'm making dinner and I don't even realize it. If your an engineering type of mindset, and like to tinker/make things work for you the exact way you want them, then RDA's and mechanicals are for you. If you want an "advanced" self dripper, and something that does math for you, then do the RBA/VW setup.
It's all about what you like
