We've only had it a month, so it's a bit early, but generally we like it.  The burner grills are nice and flat, the power burner accepts my wok ring and gives high heat, the oven provides good, consistent heat, the function display seems intuitive, and the control knobs have good "hand feel."  The griddle should be milled smooth (vs "pebble grained," to which food sticks and which is cumbersome to clean; haven't tried the grill side but I suspect it will be similarly problematic.   Overall, the unit looks good and seems to function well.
