Thing is, the price isn't crazy low compared to competitors. It's for people who are confused and don't have the technical knowledge to do something like install the unifi controller software on a debian server. If you're scared of command lines, meraki is the product for you.

6 years ago, Meraki access points were a few hundred each, and security appliances were a couple thousand, plus a hundred to a thousand per year in subscription fees. But I paid to, because ever since we did, we didn’t have to touch it, and install was a breeze. Well worth the time savings.
