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.
I would recommend this to a friend!

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.
I would recommend this to a friend!

Nice Range

This range is very nice. The only reason I did not rate it a “5” was because I wasn’t able to push it all the way up against the wall due to the coil connector and the backing on the stove has no opening to give the connector somewhere to go

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

This was just installed today, it looks fantastic and works amazing. The oven is quick to heat, the burners are fantastic, and the features are wonderful. The convection oven is a little louder than our old one at 65 db, but I don't think it's unusual for large ovens be a little louder. I cannot wait to cook on this thing!

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!

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
