Product review (1 stars): Painfully Slow!
The burners are painfully slow, and I mean painfully in the most literal sense (read on).  As was mentioned, the grates are WAY too high causing the heat to rise around the pan.  This means several things:
1) You are loosing energy to the air heating your house instead of the food;
2) Slower cooking times;
3) This was the painful part:  If you need to stir your food while it cooks, you will need to wear an oven mitt to keep your hand from cooking from the heat coming up around the pan.
4) The liquid will boil at the top edges before the core of the pot comes to a boil causing burning at these edges.

Another black mark for the stove is the knobs sit higher than the grates.  You can't slide a pan on and off without hitting them and is why several people are complaining about broken knobs.

We traded our induction cooktop for this because not all of our pots (especially canning) would work with induction.  Now I REALLY wish we would have kept the induction!  Talk about buyer's remorse.  :(
