Jenn-Air jenn-air electric smoothtop downdraft slide in range Review

We bought the Jenn-air because it was a down draft oven to go in our island. We didnt have room for the vent from above so we had to get this. This is the only down draft we could fine. Of course it cost more money which it is far from worth it. It is hard to keep the top clean, boiled over water leaves spots that do not come off they leave a foggy type mark on the glass. The stove top takes forever to heat up. The convection part of the oven I do not notice any different than any other oven. I would have rather gone with a regular electric oven than this one.
