I only use TC mode these days and have only had the Inbox for a few months. The Inbox carries a lot more liquid than my tanks, but it also burns through more liquid. I like some liquids better squonked and some better in a tank.
I notice that my squonking attys produce more throat hit than my tanks, but that’s probably a function of the builds and the attys themselves - or perhaps just because it produces thicker vapor (i.e. vaporizes more liquid per puff). I tend to run 50/50 VG/PG blends in tanks and higher VG blends (don’t do max VG liquids) in the Inbox, and currently only use regular round SS wire in all my setups. (Yeah, I’m a whimp, but it works for me.)
I like variety in flavors over the course of a day and usually have 2-3 tank setups going alongside the Inbox, but I do reach for the Inbox more often than not.
I’d buy another Inbox if mine was lost or broken and I will probably pick up another TC capable sqonker in the future. Maybe a Therion...
What else can I say? You just gotta try it and see for yourself. I’d wanted to for a long time before I bought the Inbox and I’m not sorry I did.
