So because everyone wants to make profit, nobody can complain about any prices regardless of how insane they are? What kind of logic is that?

It's honestly not even that expensive considering all the functionality you get and the tech included (which is something HN should understand)

The functionality is a small screen with a timer and a few API calls to set the timer for you sometimes. $189 for a timer is not a lot of functionality for more than 1% of the annual salary of a minimum wage worker. You can get a full android phone for that much which has 10000x the functionality.
