Product review (3 stars): Works beautifully and looks great - but a nightmare to keep clean!
Pros: Nice, consistent, even heat distribution. Lights easily. We have been using ours a year and it seems durable to me so far - no wear or tear on any of the parts. Looks gorgeous. Cast-iron racks are solid and sturdy. Different sized burners for large or smaller pots.
Cons: You can't get it to look clean unless you take the whole thing apart and clean it after anything you do on the stove. ANYTHING that lands on its surface mars its pristine looks - even drops of water. Boiling water in a pot with a lid? Once you take the lid off, drops of condensation will land somewhere on the stainless part.
You think, "No problem - I'll just wipe it down when I'm done." But when you try, you just sort of end up moving the splotch to a different part of the stainless steel - like the knob platform. "Well, no problem...I'll just pop these knobs off and clean right under them!" you think.
And you do, but then you notice that the sides sloping down from the knob platform now look sort of grungy and just different from the rest of the stainless steel.
"I'll just take off this burner rack and make it all look nice," you think.  "And...I guess this one, too. And while we're at it, there's only three of them...so..."
At this point your cooktop is totally naked, so you have an unfettered view of your handiwork, which is terrible. You decide to do an overhaul, working in long strokes with the grain of the steel. After about five minutes, you step back to admire your work.
But what's this?! Apparently the cleaner you're using has seeped into the cleverly-made rubber valves under the knobs, where evidently some grease was trapped - probably from the bacon-fest you indulged in last weekend, after which you swore you'd only ever boil water on your stainless steel cooktop going forward. The grease has broken down because of the exposure to the cleaners, and is seeping out onto the stainless steel, making angry streaks on the knob platform.
You take off all the rubber valves (they are easily removeable - put that in the "pros" column) and soak them in a cleaning solution to rid them of any grease and start the whole stainless cooktop cleaning process all over again.  When you're done, you step back to survey the results...a streaky disaster, because now there's GREASE involved. So you start again, and finally are happy with the results.
You retrieve the rubber valves from their soaking bath and spend a minute or so drying each one - at this point, you know they must be TOTALLY DRY or you might get a drop of water on your stainless steel cooktop, which is how this all started.
Then you put the burner grates on. They're heavy, and the leg of one of them hangs on another of the burner grates, and its little foot cushion pops off (Replacement feet exist, are called "General Electric GE Gas Range Grate Rubber Feet" and are available right here on Amazon!). You watch in dismay as it bounces and rolls across the kitchen floor into the waiting mouth of your dog, who swallows it, then sits down and cocks her head and looks at you like, "That treat was terrible. Don't you have anything better? Didn't you once cook REAL FOOD on that cooktop?"
You replace the burner grates - now one of them sort of wobbles, and decide that somebody should really warn consumers about the hazards of a stainless steel cooktop - ANY brand of stainless steel cooktop.
