My current microwave is 20 years old. It has a lot of buttons. I love the buttons it has. It's sensor modes are spot on.

I stab a potato and cover it in butter and salt, put it on a plate, press "potato" and it's cooked just perfect every time. Doesn't matter if it's big or small, it's just right.

When I have a plate of leftovers I just press reheat and it's perfect pretty much every time. Could be pork chops and Mac and cheese, could be a spaghetti with marinara sauce, could be whatever. Toss it in, lightly cover, press reheat, and it's good.

When I want to quickly thaw out some ground beef or ground sausage, I just toss it in, press defrost, put in a weight to a tenth of a pound, and it's defrosted without really being cooked yet.

Back when I microwaved popcorn, just pressing the popcorn button was spot on. Didn't matter what the bag size was, didn't matter the brand, the bag was always pretty much fully popped and not burned.

Despite being the same age it's still in excellent working order while yours with the dials fell apart.
