Yeah I was able to get two from an alibaba seller for like $90 or so, I posted a link to a seller in the x-max thread. They would also sell one, but it's nearly the same price so get two and share with someone (or buy even more, then they're even cheaper!). Just make an alibaba account and message them, they'll try to work something out.
Anyway its too early for my review, but I will say its been going smoothly so far, although one tastes better than the other I think. I mainly have only used blue/374F bc the next level 410F is already kinda too hot for me usually and where the taste goes south real quick on either vape. I have gotten 3 or more two minute sessions just at blue though, so the short sessions are nice for a quickie and less waste, but you definitely need to run multiple sessions on a full load to cash it (unless you move up the temp ofcourse, but itll still likely take more than one session).
So I really wish it had like a 385 and/or 395 instead of 410 and/or 446, bc 374 is quite nice but I'd like to be able to get closer to 400 without going over it... I understand the higher temps are for concentrates but that's pretty useless to me so its a little annoying (but for this price I don't mind it so much, and I can always use those high temps to get really blasted really quick on the go if I need it, like for a movie it should be good).
However, the other negative is the mouthpiece, as it is quite restrictive airflow, one of the most I've experienced (maybe only slightly better than the FlowerMate). That little screen gets clogged up with herb as you pull, so you have pull extremely hard to get clouds I found, puffing on it works for this. The mouthpiece also gets hot with back to back sessions as well, and as others have said, cleaning will certainly be and issue with the plastic and unremovable screen.
I also wish there was a mouthpiece with 18mm connection, like the T-Vape had, so I could enjoy those higher temps more. I do like these better than T-Vape (and possibly FlowerMate too) in every other way though, simpler, so far more consistent and reliable, and battery life seems pretty solid so far too (a little over 45min maybe? I didn't run it down, but I did seem to get like 20 two minute sessions at red/446F during my burn offs and the battery hadn't even died yet at the point, but it did take a little while to charge back up so it must've been close.
More forthcoming...
