This appears to be a high quality product. The sensor reheat works well and certainly beats having 10 different buttons for different foods. Haven't tried sensor cook yet. I wasn't sure about having a knob to set the seconds, but it works well and most of my family members prefer it. Now I really bought this microwave because of the inverter technology. I cook a lot and melt things like butter and chocolate - and I'm tired of the butter melting in the center, then spattering all over the inside for a few seconds, even though I have it's set on power level 3. This microwave really does what they advertise - power level 3 is 30% power, NOT power level 10 for 30% of the time. It WORKS! And that alone makes it worth the extra money. The only negative I can think of is that it's rather short, height - wise.
