I recently acquired a Ruby Twist (had been using a Flowerpot (?) B0 for my ball vape).
Outside of it being considered an 'entry level' ball vape, I dunno why it doesn't get much mention on this site (I did search).
The 'fan shaped' section of the underbelly really does distribute air across the entire load. VERY even extraction; I never have a 'oh, I didn't get the maximum out of that load' (and I don't go all the way to 'crispy' (near / at pyrolization), although I could.
The downside of the thing (for me) is the limited load size. Only the matrix (Ti) bowl is recommended for heat soaking, and according to VGoodiez, the only other bowl that will fit / approved (that I don't have) is the Ed's TNT version. Which looks like it really doesn't hold that much more.
But the Twist is good enough for me that if they released a version compatible with more standard bowl sizes (and glass is fine; I don't break it)... I'd buy the updated version.
Now to jump to my next acquisition (maybe I'll use part of my upcoming tax refund to offset) is the new Tafee Bowle (sp?). I hear such great things about it, but if I wanted to pay $400 for a vape, I'd be looking at 'german enginEERing' with something from S&B. But that goes with the same reason I've never owned a BMW. No offense to Germany; my 'mutt' pedigree says I have some heritage, there. I do wish Japan was more forgiving with cannabis; I'd love to see what they do with TEDs, comparing their automotive prowess against Germany's (and I don't wish to take this off-topic with 'who builds the best cars for the $')
I've used this site (among others) to pick out 'best of breed' for the type of vape I want (hot stick, battery portable, corded). And for the most part, the recs have been spot-on, once the learning curves have been accomplished. I know we're all looking for 'something better', 'new', etc. -- but once I have something that works and is reliable for a particular use condition, I stick with it. The one thing I'd get involved with 'new' is if a vendor offered me a pre-release device for eval / recommendation for improvements. That, I'd love to do. Even if I had to pay for it (because my goal isn't to get 'free shit'... it's to get my hands on the current / upcoming ne plus ultra of devices, to make them work better.
