Product review (5 stars): We bought it years ago and have loved it every step of the way
This review is for the Bosch NIT5065UC, not the 5066.  We bought it 2 years ago and have loved it every step of the way.  Amazingly fast, efficient, turns itself off if a pan runs dry (scorches still but not badly).  Easy install, and has performed admirably so far.  Fingers crossed it lasts long enough to justify it's cost, but the simplicity of cleaning and the fact that i use it as my main countertop for food prep (not recommended by manufacturer) since it remains a cool-ish surface to work on means it makes my kitchen feel larger besides.  A+ favorite appliance in our house.

Update:  it's been another year and this is still one of the best appliance purchases we have made.  it brings constant savings of time in reduced waiting time for large pots of water to boil (I can fruit, make large soups weekly, etc) AND it only needs to be wiped down so it saves all the time I used to spend cleaning stovetops!  LOVE this cooktop fairly madly.
