That’s insane. I actively avoid buying things that are pointlessly internet connected nowadays. An air purifier’s buttons should be simple electromechanical switches.
By "touch buttons" possibly he means that they are "buttons" on a touch screen. What's crazy to me is that this is now cheaper to put in a product than electromechanical switches.
It's a Mila, they're capacitive touch buttons but not a touchscreen. There's just a fan down, fan up, and mode button. Even still, I don't know how they got the calibration wrong enough at the factory that it can't detect a full-pressure thumb press.
