Happy to discuss any of these bad boys! All but the VaporGenie see regular use. I also got an old MFLB stashed aways somewhere that I bring out maybe once a year or so for a sesh but I forgot to include it in the pic and can't be arsed to take another one rn.
BAK took a bit of playing around with settings and there were some shenanigans with the connection integrity that I had to figure out, so maybe not the best if you don't want to tinker a bit for a great experience. Herborizer is as easy as it gets though, turn dial to your preferred heat setting, wait a couple minutes for it to fully heat up and then hit it whichever way you want. Sure, you need some trial and error at first to figure the perfect settings but once you do, it's super consistent every time. Actually that last sentence goes for both of them, just more things to figure out with the BAK. Not that I'm opposed to more manual vapes, mind you!
