I have a kitchenaid dryer from the 80's with multiple selections for dryness levels and it works great every time. I can leave the clothes a little moist if the air is dry and I'm going to hang them immediately or set them to completely dry, in case I'm going to be away when they are ready.

My parents' modern dryer is awful, just like yours. The craziest part is that it starts a countdown timer when there's tens of minutes left, as though the designers new the sensor was awful and decided to add some extra drying time to cover it up.
