Yeah, I'm one of those that has to have a distinct throat hit. I was using the KM3 and loved it. Tried the K5s, and just couldn't get the solid, condensed vape. I was really looking forward to the Prime, but it was kind of the same. I tried dozens of builds in it, and just couldn't get there with the TH on any setting. To me, it just seemed kind of "diluted" with air, is the best description I can give. I gave it away.
Tried the Doggystyle, and it's been perfect - easy to build & extremely forgiving, consistent, great flavor, no leaks or condensation, not a single issue. I tried the Dvarw out of curiosity. I really like it a lot - vapes about as good as the doggy, but too many parts, o-rings, issues with that cap sticking. And you have to wick just right, or it'll leak. It's a great little tank, but it just didn't do anything better than the doggy for me, so I gave it away too. But I wouldn't discourage anyone from getting it - it does deliver a great vape.
