Need your thoughts Looking to perfect a conical coffee grinder

Hey coffee lovers!

Currently in the midst of perfecting a conical coffee grinder - woohoo! It's a conical burr grinder for coffee (and spices) with an IoT-connected hopper that allows you to measure bean freshness and volume and receive replenishment alerts or auto-replenish when it's time for fresh beans. It's unlike any of our previous products, but we're a big (actually rather small) bunch who love coffee. Just have a few general questions from the top of my head that I'd love to gain some insight on.

What are some of the most important things you look for in a coffee grinder? What do you want to see in future grinders that isn't on the market already? What's one thing current grinders on the market lack/fail in?

On a similar note, how do you feel about the idea of coffee subscriptions with the grinder? And grinder portability?

Excited to hear your thoughts!!
