This oven stove combo is larger than your typical residential oven but smaller than Commercial
Six burners on top in a very large oven
I also like the additional features of the blue light

I am very happy with this oven! A huge step up from my old 2014 NXR. Super easy to install…I did it myself (+ gas hookup)! Easy to clean, oven heats up fast, solid digital oven controls and burner knobs. Excited to cook again!
I would recommend this to a friend!

Recently replaced similar oven with Cosmo. The digital temperature control panel is nice. Overall, it's a great oven for the price!

Commercial grade cooking made residential

I love how much cooktop space there are with six huge burners as well as the massive oven capacity. The visual design is very beautiful and fits my kitchen island perfectly. The only thing I would improve is the cooking interface screen the buttons take a little bit longer to set my cook settings than standard ovens. I think for the price point, I would expect a little more advanced interface, but all of the built-in features and settings for cooking features make up for it.

Excellent stove for our new home. Love the 6 burners, multiple baking settings, and ability to change oven temp by one degree at a time. Highly recommend.
