Why do manufacturers still release products like it's 1980. I can hear when it's done, because the unit has turned off about when I expected it to.

My combo microwave/air fryer beeps if you take food out and close the door before the timer is finished, like it doesn't know what to do now.

My Breville toaster oven has three beep settings: incredibly loud, ear-splittingly loud, and off. It still runs the fan when the timer is done for a while too, so there’s no good indication there. So annoying.
