Product review (3 stars): Silly Design Flaws
We got this unit as a pair with an Electrolux dishwasher, which I've also reviewed, and has been nothing but trouble.  This is a beautiful range with a lot of nice features.  It is all electronically controlled, has convection, the sliding racks are great, and it feels well built.  But it has one of the silliest design flaws, which I cannot believe was not detected by the engineers.  The racks above the burners, the small removable rings around the burners, and the topmost part of the burners are cast iron.  They look great when they are new, but once you start cleaning the unit, they rust, discoloring them and leaving rust stains on the stainless steel which you cannot get out.  Its very similar to a cast iron pan which has rusted.  I cannot believe that something else could not have been used.  I've used many gas stoves, cleaning all of them the same way, and never encountered such an issue.  Its really odd. Additionally, the largest burner which is hollowed out and encloses a small pilot inside, doesn't light well.  Essentially you have to run gas into it for a few seconds, filling the hollow portion with gas, before engaging the electronic igniter.  The result is that when it lights, there is a large "poof" of flame which jumps out at you.  My wife won't even use this burner.  So, overall its a nice unit, but these silly flaws seriously detract from it.  I wouldn't buy it again.
