Product review (4 stars): Mostly love it!
So far we like this model, cooked Thanksgiving dinner in/on it, everything cooked great, had stuffing/dressing and green bean casserole in the top oven and a 13 lbs turkey (could easily fit bigger) in the bottom.
The middle griddle is awesome! I have been able up to make 8 4" pancakes at once.  as many as 6 pieces of French Toast, 6-7 bacons and sausage and grease did splash everywhere (same with any stovetop) but grease went in the channels and didn't overflow.
Large cooking surface, grates allow for easy movement but resist slipping.
Controls were easy to learn and use - would be nice is you could set volume controls because the alerts, albeit pleasant, are not very loud.

Cons:
Only convection in the bottom oven, also we have not had much luck with the convection oven.  we tried cookies, one batch we cooked regular (w/o convection) and they turned out great.  We cooked with convection and some burnt and some cooked perfectly.  I thought convection was supposed to cook faster and more evenly.  that said we just moved from TX to CO and we are living above 7000' for the first time, so we are learning to cook all over again.
We are in our mid 40's bending all the way down to get things out of the bottom oven can be difficult, especially things like a heavy turkey.
Only came with the Griddle from Lowes we want to find a grate and the middle grill, we are having difficulty finding the parts.
