Product review (3 stars): 3.5 stars would be 4-4.5 if simmer better and no parts problems (ignition and knobs)
I guess I would give it 3.5 stars overall but its difficult to rate this on one category so let me break it out:

Parts:

Ignitor sometimes keeps igniting (clicking) even when flame is on full throttle, knobs loose/come off.

Design

Looks great, cooktop comes appart easily for cleaning depth of cooktop is great. Oven is nice depth could be a little bit better but its fine.  I have had things slid out and fall out of the oven, its level but the grates wobble a little, be careful slding food out, I cant really work with in on the rate, need to remove it completely form the oven, do my work (stir, flip a steak etc.) and then put it back in.

No clock is no problem at all.  I use the clock of my other oven and its fine.

Installation:

Leveling the oven is a PAIN.  You and to have people lift and hold it while you fiddle with all our legs. Taking the door off is a breeze and a must when installing.

Cooktop Performance :

Love the depth, you can have 2 large pots or pans front and back and still center on the flame, no problem.
