Product review (4 stars): attractive and functional, but be prepared to clean it every day
This cooktop works just fine, and we are glad to have it as there are very few smaller gas downdrafts out there. But oh my heavens, it is tough to keep looking clean. Every speck of water will show on the lovely, shiny surface. Simply boiling green beans, for instance, will kick out hundreds of tiny spots onto the surface. Know that a simple wipe-down will not do the job. To clean it so that it, you know, LOOKS clean requires removing both burner grates AND the four knobs. This is not difficult in the least, but it does take effort and time. Now you will wipe down, or use the Cerama-Bryte cleaner for tougher spills. Then you'll notice that the surface looks merely smeared rather than shiny and clean. Here you will need a good microfiber polishing cloth. After a firm polish with the cloth, your cooktop now looks clean. Replace the grates and knobs and you're ready for the next meal to be cooked.

I do notice that water takes longer to come to a boil when the downdraft is activated. I hadn't expected that, but I suppose it makes sense, given that some of the heat is being pulled down and away from the pan.
