Puts the big brands to shame!

I replaced a top of the line Frigidaire with the Cosmo COSC5EIX and I could not be happier with my decision. I was a bit scared to stray from the big name makers of appliances but I did my homework and saw that Cosmo had great reviews so I decided to give them a try. The install was a breeze. The performance is second to none. It does everything a regular oven does but it does it all BETTER. The look of the oven is amazing. It is a show-stopper and I've received more compliments on this than my Wolf appliances. The pop out buttons/knobs are such a simple but fantastic design esthetic. The oven functions are plentiful, with 7 different baking modes, and they all execute beautifully! The rack system is unreal considering the compact size, with 10 options for placement of your oven racks. The fit and finish are top tier. Thank you Cosmo for the fantastic craftsmanship at an unbelievable price!
I would recommend this to a friend!

We just had it installed and we have used it a few times. It was easy to set up following install. Functionally, the convection aspect is very satisfying. In addition, the stainless steel appearance goes well with other appliances.

We have an older home and our previous wall cut out had very specific dimensions. Most popular brand ovens were simply too big. We have just had the new Cosmo oven installed and so far, it’s great! Easy to use (read the Manual though) and it’s beautiful in my older kitchen. I will need to add a piece of trim to the top and bottom to finish out the size of the cutout. But I’m loving it!
