Product review (5 stars): Agree with complaint about the front right burner
My wife and I have had our Kitchen Aid duel fuel range (KDSS907SSS) for about a week and while we've not yet used the oven we have used the gas-stove top.

I read a number of negative reviews of this oven. The three main gripes I've read are 1) about the low BTU output on the right front gas burner, 2) that the control panel buttons can easily be pushed if you brush up against the panel, and 3) something about the oven venting on one side of the door and that this causes the oven door handle to get too hot (and something about water condensation building up and then dripping down the front of the oven door).

I cannot offer any feedback about #3 above since we have yet to use the oven, but I can tell you that the first two complaints listed above have merit.

The control panel is "very touchy" and I've inadvertently hit various settings by brushing my lower torso against the panel when reaching up high above the oven. But I suppose I can get used to that.

But I am very concerned about the low BTUs from the front right burner and the rear left burner. I just ran an experiment to test this out (and filmed it for eventual posting on YouTube) in the following manner:

I took 4 standard small kitchen pots and put 1 inch of water into each of them. I then lit each of the 4 burners and set each burner to high. I put a pot (with 1 inch of water in it) on each burner and started the timer. And in case you are wondering, I live in California at about 50 ft. above sea level.

As I expected, within a few minutes the powerful burner in the front left position brought the water to a boil. The rear right burner (the second most powerful burner) achieved a boil next. I'm not unhappy with the performance of either of these burners.

The left rear and right front burners (which both have the same BTU rating) took much longer to achieve a gentle rolling boil (I'm not even sure I could call it a boil... there were a few streams of bubbles coming up from the bottom by the time I ended the experiment, but I don't know if I'd classify that as a "boil"). It took 15 minutes for the left rear burner to achieve this, and over 16 minutes for the right front burner to achieve this.

Pretty disappointing. We switched from electric to gas with the thought that we would get instant heat with the gas-stove top. Well, we get instant heat all right, just not enough heat to boil 1 inch of water in a saucepot.
