Excellent range for the money!

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 would recommend this to a friend!

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

Haven’t had a chance to use yet but no issue with any damages, It was packed very well and it’s stunning. Went from electric to gas; I’m sure I’ll appreciate the change.

Sexy

I purchased my Cosmo range 2 months before my kitchen Reno was far enough along for installation.Upon seeing my range the words out of my mouth were “Now that’s sexy as hell”. I never thought I I would feel that way over an appliance, yet, every time I walk to the kitchen that’s how I feel.
I would recommend this to a friend!
