Excellent review. Really glad to see $300 products given "$300 worth of scrutiny".
I really don't understand why a few phone brands won't produce a cheap $150 webcam with an average-for-phones sensor, a decent lens, and some old Qualcomm DSP from two years ago. They already have massive volume discounts on seemingly everything, right? It must be much harder than I'm thinking, right? I know, low volume, weak clients, etc., but near everyone I've worked with remotely has often complained, "Geez, I look like a goblin. Stupid windows".
I guess the market is too tiny and the margins still too small. Seems prime for brands like Samsung, Xiaomi, LG, OnePlus, Sony, etc., that have a "lifestyle brand" anyways.
