A great cooktop with good heat and constant flame.  We like the fact that the grates are closer to the burners than other brands.   Reason for 4 stars?  Our 20 year old WOLF had thicker metal.  The BOSCH cooktop (as all newer cooktops) has a thiner/lighter metal.  We understand the various reasons for that fact, but it  makes the product look and sound cheaper than our older cooktop.  Other than that, we're quite happy.
