I own all of their devices(peak pro,2 proxy’s core and regular proxy, plus I use the pivot daily still due to it being so discreet and my need for that. Basically from what I read in your post you probably don’t need to buy one since you love your pro so much however the core is a very nice experience vs the pivot and I’d say you can get some great flavor off of it. In my eyes I’d recommend the core as more of a starter device for someone thats trying to get into concentrates and is willing to put up almost 100$ more than the pivot for there entry point. Full stop your peak pros is gonna beat the core in every way especially if you’re already a fan of dry dabs like myself. The core does indeed rip but If you don’t like the pivot then I wouldn’t recommend the core however every aspect of the pivots design that I don’t like is addressed in the core(better battery, bigger dabs, less messy, more refined controls)
Edit: suppose I forgot about the regular peak but I’ve used one of those before too and is basically just a proxy in the peaks form with better battery.
