Product review (1 stars): Would I purchase this range again? No.
Ive owned my Kitchenaid commercial range 2.5 years now. I have much to say about this range. Above all, would I buy this range again? No.

Heres what I don't like:
1. NOISE. It has a convection oven that you cant turn offoperating it without the convection fan grinding away is not an option. Oh the noise! I knocked out a wall between the family room and the kitchen during a remodel (hence the new range), and so we have to listen to this racket in BOTH rooms when Im using either of the two ovens. Hate it! Hate it! Its such a relief when the food is done so that I can turn off the oven.
2. Computerized board (or whatever you call the brain thing that operates the range) quit working within the first 90 days. Just died. It was probably defective when we got it. Fortunately the unit was under warranty. Still, taking off work to have a $6,000 stove repaired within the first 90 days of ownershipnot cool.
3. Lighting. I mean lighting the burners. If you do not have the round metal covers that sit over the gas holes exactly in place, the burner won't light when you turn the handle. It clicks and clicks and clicks but you get no flame. So you adjust and adjust and adjust (you have six burners to adjust, remember) trying to get them in the right place. Annoying. Ive come to hate cleaning the stove top because I know that Ill have to waste so much time adjusting the dang gas covers to get my stove working again.
4. The griddle. Wanted a griddle for years because I have four kids to make pancakes for in the morning, so I ordered the model with the griddle. But the griddle is electric and it takes a full 20 minutes to heat up. Want a quick something fried on the griddle? Forget it. Takes too long. I end up throwing a frying pan on the stove instead. I never use the griddle because of the terrible delay in heating it up. Its no fun to clean either. In fact, the few times I have used it I spent far more time cleaning it than I did cooking on it. And its made of a shiny metal that scratches, so it doesnt take long to look beat up.
5. For all the space this unit takes up, it should have a small warming oven. I had a warming oven in the cheap GE double oven I had before I remodeled. The total oven was smaller than my Kitchenaid range but still they managed to work into the design a large warming oven. I sure miss that thing.
6. The kick plate at the bottom of this range has a large tray (or gaphard to describe) which food falls into. You can see the dirt but you cant reach your fingers in there to remove it. Now a kick plate is nearly at floor level and gravity is in operation here, so all the bits of food you drop while standing at the stove make their way downward toward that kick plate. It never looks clean in this area, and there is nothing I can do about it.
7. The area under the grates is quite deep, shiny black porcelain. EVERYTHING falls into this shiny black pit. Its like a permanent trash pit. Consequently my stove top never looks clean. A flat stove top is easy to clean, just wipe, wipe, wipe. But because this is so concave you have to vacuum first to get up all the dried food, and then you have to wipe. So most of the time my stovetop looks dirty even though the rest of the kitchen looks clean. I just don't have time or inclination to drag out the vacuum cleaner every night.
8. Only one of these two ovens is self-cleaning. So, after $6,000 for all this convenience, I still have to get down on my hands and knees on a hard kitchen floor to spray the narrow interior with oven cleaner and wipe and wipe and rinse and rinse and turn myself into a pretzel to get my oven clean. Annoying.

What I like:
9. The unit looks handsome in my kitchen.
10. The burner grates are heavy cast iron. To clean them I simply put them in the oven and run them through the auto-clean cycle. Dried grease and dirt turns to ash and I just wipe it away.
11. Six burners are nice. You may not use them all at once, but youll always have enough clearance between large pots if you are cooking, say, four things at once.
12. Meat probe. You set the internal temperature you desire and voila! Your meat comes out perfectly and the oven turns to warm the second your meat is cooked.
13. The high level of BTUs means you can truly bring a large cooking pot to a rolling boil.
14. Anything built of stainless steel is desirable in a busy kitchen.

I paid too much for this item. If I ever get bitten by the remodeling bug, I will look at a different brand of stove. Sad. I always had the highest respect for Kitchenaid, but this range is a disappointment.
