I got this microwave because I wanted a microwave that was cute and matched my teal kitchen, as I don't currently have one installed in my new kitchen. This option was the largest and most powerful teal microwave that I could find on amazon. It is still less powerful than my last microwave so I think it will take some getting used to when setting times. The cook times are adjusted by the lower knob and are increased or decreased in 10-second increments. It is easy to bump up or down the time even while the microwave is running. The longest you can go is 60 minutes. But I have never used a microwave for that long, so not sure why you would need to go higher.As other reviewers have said, the microwave will continue to beep if you do not remove the plate. But it does not bother me as it is only every 3 minutes. I've had microwaves that do it much more frequently, so 3 minutes is a long break between beeps. This includes when you remove the plate early. So if you want it to stop, hit the cancel/clear button.It includes most of the same features as a typical microwave. There are no preset buttons (i.e. for defrost or popcorn etc.) But there is an Auto Cooking selection on the knob, which includes options for popcorn, Reheat, Beverage, Pizza, Potato, Vegetable, Meat, and Fish. And you can turn the knob to 3 different power levels and defrost by weight. There is also a speed cooking option which says it wets the microwave to "high fire" But I don't know the difference between that and setting the microwave on high.The internal measurements are 11 inches by 13 inches. It is large enough to fit my biggest plate which measures 10.5 inches, which I was worried about when I ordered it. The exterior length is 19.5 inches. It will sit away from the wall about 1.5 inches and the total width from the wall to the tip of the handle is about 15 inches. The height from the countertop is 11.5 inches.Overall, it is a cute countertop microwave that is doing what a microwave should do.
