We just received our Cosmo Range 10 days ago and are very impressed!  It arrived quickly, well packaged and in perfect condition, was easy to install, it has baked homemade pizza crust, pumpkin bread, and a roast to perfection, as well the gas stove is working beautifully with the 5 burners offering 4 different heating options-we have had no problems whatsoever.
I was looking at Thor and Viking as an option after reading about some issues with this Cosmo model and I'm very pleased that we decided to save $1200 and try the Cosmo! Great purchase for the money!!
