To clarify the question - the knobs are CHROME plated. They are not a solid metal piece. The grates are cast iron. Here is a link that might be useful: Verona Home Page

Just bought a vacation cabin that came with a gas Gemini. While I'm not a fan of gas, I am in love with the double ovens. I have not used the lower oven to date. The upper is so handy! I will say the broiler in the upper oven is much better than any electric I've used. Main house has a smooth top electric which is a winner for ease of upkeep, but when it dies there will be a double oven unit of some sort replacing it

I considered Five Star while researching my cooking choice for my kitchen remodel. I was set to buy one based upon reading their literature. I called the Five Star company and discussed my questions with one of their people. They referred me to a cooking school in my local area that had Five Star ranges where I was able to see, test drive and discuss the performance with the cooking school staff. The ranges are owned by Five Star and provided to the cooking school for display, "test driving", etc. since they do not have a distributor in the area. The report from the staff was not great. They said the ranges (they have two) all too frequently required burner and oven repairs on both of their ranges. The day I was there, both ranges were waiting for repairs--one oven wasn't heating sufficiently and a total of three burners on the two ranges were not operating. Most of the time they have to use long reach butane lighters get the burners going. Service is difficult to get even though they are in one of five largest cities in the country. Their opinion was the Five Star is impressively marketed but cheaply built and problematic. They said the burner performance stats are impressive in the literature but performance is weak in practice. They said if they were buying for their homes they would spend a little more and get a better built range. And that's just what I did thanks to their advice. Hope this is helpful to you.

Forget I asked that question. Have decided against the Jenn-Air because of so many complaints with Aqualift oven cleaning system.
