This replaced a larger Sharp Carousel I had for years. It's taking a little while to get used to the time buttons on these, which are a little different. I like the "Extra 30 Sec" button, for instance, and I really love having the ability to mute the timer buzzer, which is too loud and annoying to listen to on any kitchen appliance. Being a little smaller than my Carousel, it seems to take a little longer to cook or heat things, but for me it's worth it so I can have a mess massive box sitting on my countertop and taking up limited counter space.
