I have both, and then some lol. As of right now, it's a toss up for me. I like the bar style firing, but it's hard to push, for ME. The Primo Mini, I don't really have anything bad to say about it, it will sometimes take a second push to fire, and that's why I kept buying other mods, but I'm learning that they all do, again, for ME. As I've mentioned before, probably at nauseum bc it's completely relevant to MY vaping, I have a lot off health stuff and my hands aren't very strong, maybe I'm not applying enough pressure to make them fire every single time. I will say that I prefer the menu interface of the Primo Mini, but only bc I was coming from another eVic product, so I'm very familiar with it. I don't have a single doubt about the durability of it, their products are solid! BUT I can't use that as a con towards the P80, I've NEVER used a Wismec product before. I know that I thought I would like the feel of the P80 over the Primo Mini, but I'm finding that that's not really the case, the Primo Mini fills MY hand better, so it is easier on MY hands. I honestly think I may have gotten a defective P80, I've had some strange issues with it, but it's mainly around the firing, so again, it could just be that my hand isn't strong enough for its firing bar. Oh, and I don't trust the finish on the P80 as much as I do on the Primo Mini, but then again, I know eVic products are made to last!
Anyway, that was all probably useless info lol, but that's my thoughts. I took a pic, but I don't remember if it was for this thread or the Primo Mini thread, of the size comparison of the 2, and some other mods.
