    Attractive, affordable sharp- looking badic range

    The range is sleek and modern looking. The two front burners have small/large burner options. The two back burners are for small pans. The stove has conventional and convection settings for bake & broil, convection roast and defrost options. No fancy smart phone/wi-fi connections. Just a solid, basic range and affordable.

    A beauty

    Initial order came damaged but replacement arrived early. Range is a beauty- defrost, bake/broil and convection oven all rolled into one. Would recommend!

    Just got it, turned on the convection bake and immediately there is a pop and smoke. The fan blew out and singed the back.

    Stylish, Reliable, and Cooks Perfectly

    I absolutely love my Cosmo Electric Range in stainless! I wasn’t familiar with the brand before, but after some research I decided to try it—and I’m so glad I did. It’s stylish, functional, and the convection option has been a game-changer for both meals and desserts. The only thing missing is a self-cleaning feature, but that’s a small trade-off for how well it performs. I also purchased a Cosmo dishwasher at the same time and couldn’t be happier with both appliances!
