Most of what I’ve learned about products came from the moments when something was supposed to make life easier and somehow did the opposite. Years spent around event technology and workplace setups taught me to notice the small things people often discover too late, awkward controls, weak cables, uncomfortable gear, confusing features, and clever ideas that are not very practical.
Confer Cal grew from that habit of paying attention. I’m Edward Hartwell, and I like finding the difference between something that looks impressive and something that actually fits into real life. That is the perspective I bring to every recommendation I share.
