I just wanted enough to keep me off the cigarettes. In late 2009, I tried those first-generation cigalikes. Good idea, but not impressed. Later, I tried the pen-style. Better, but not enough. Then the 510s, and I didn't really like those at all--everything tasted burnt to me. Fast-forward to 2013, I had read the eGos were "the thing". So, I got a starter kit, and I did indeed quit smoking. But after about 6 weeks, I could feel myself faltering, so I did a lot of reading here, and within a couple of weeks ordered a Proveri 2.5. I thought it was amazing. Just after that, I also began to DIY. Last year, I also bought three SIDS on sale, two of which were for gifts, the other because I wanted to try it myself. They were okay, but not the same smooth vape as a Provari, and they don't hold up well. All three conked out within less than a year.
Last year, I bought another Provari 2.5 for a backup (which has never been used yet) and just recently bought the Provari Classic 2015 (for the variable wattage factor), which I am using now. I compared the Classic with the P3, and I chose the Classic over the P3 for several reasons:
1. I have no intention of going lower than 1 ohm, so I wouldn't use the 0.5 ohm or whatever is the lowest at which the P3 will fire. I think the Classic will fire at 0.9 ohms, but I use mostly 1.8 ohm coils, so that's not a factor.
2. Button colors--the Classic has a couple less button colors than the P3, but that's also not a factor for me. As long as it blinks to warn me the battery is getting weak, I don't really care about button colors.
3. I liked the teardop design of the Classic more than the plain design of the P3 with the logo.
4. The Classic was less expensive than the P3.
Really the only reason I ordered the Classic was for the VW feature. And since my other two were only standard size, it's nice to have an all-in-one size now (mini, standard, extended).
BUT, since I've bumped up the watts to 8.8 (DON'T LAUGH!), I've noticed I use more juice now. I can't imagine you guys who sub-ohm and use so much e-liquid every day. I can live without that, thanks! This is keeping me off cigarettes, and I'm very happy and still amazed it works. On July 2nd, I'll be smoke-free for two years, YAY!
