Yeah this is my first vape but I've tried other vapes before.
I would say that it will be fine as my only one, after buying the pax I don't plan to spend money on another vaporizer for a long while. I can get clouds that are big enough to rival the hits I've taken from the bags of other vaporizers. I would highly recommend that you inhale on the pax softly and slowly, the longer I make my draw last the bigger clouds I can get.
I filled the oven with about .3 g and packed it down, I got around 15 or so draws, I had enough draws and vapor production that i was happy enough with the efficiency, because compared to smoking that same amount i got much more out of it.
I also was choosing between the solo and the pax, In my opinion considering that the vapor production i get from the pax is good enough, I would say that the pax is better for my situation.
The pax is so easy to use, quick to load and empty, that sounds trivial but the ease of use is surprisingly one of my favorite things about it. I love that i can pack the pax, go use it whenever i want after having packed it, and if i don't finish it in one session i can just turn the pax off and finish it at my leisure.
I've never used a solo so you might want to ask someone who owns one, but the solo has a glass stem and is much larger than the pax so that makes it harder to use on the go. I would say the best reason to get the solo over the pax is because its cheaper, but if you can spend the money I would recommend the pax over the solo because it is so much more portable and easy to use.
Also the pax looks cooler than the solo, I would also recommend looking into the da vinci ascent, but that isn't out yet and is sure to cost a pretty penny as well.
