My two cents on the battery and Mighty/Crafty debate:
Mighty sure kicks ass but for those in a non weedist country (talking more about social acceptance than law) it may rise too much questions if used in public so it may just not be an option in all cases... just too big and the screen gets too much attention to be discreet, that's why I chose Crafty.
For home or private use though is a killer but so would a Volcano or a Plenty and clouds quality apart imo these seem to be more long lasting choices due to the failure ratio of portables atm.
Guess in the end it mostly depends on your mobility/power/discretion priorities, social acceptance of weed in your routine, budget and personal circumstances.
In my case I end up carrying a fuckin hardware store with me at all times cuz I panic being left without juice, two or three portables and the powerbank so I'm not precisely saving space but prefer it since can use all of them without arising uncomfortable stares, which I sure wouldn't be the same with the Mighty. At home I use a Volcano but I'll prolly end up selling it and getting a Mighty instead when my child grows older, unless I find a way to conceal it or something better comes in the way.
Until the development reaches a point in which we can have a big load capable 100% convection long battery lasting pen sized vape (looking at you grasshopper) there's only a limited set of priorities each vape can satisfy and for so it's more of a custom approach rather than a broad style product. What will we do with all the VAS when that day comes?
A final comment for S&B on this one. Was it that difficult to make the battery swappable guys? I'm guessing half of your service returns were due to faulty batteries so it would've already saved you a lot of trouble...
