Product review (1 stars): No heat after first use.
I tried this burner out as soon as it arrived.  It boiled a cup of water faster than a microwave.  I used the same pan for dinner.  Upon turning it on, I selected "sear" to cook my food.  At first it didn't want to heat.  I adjusted the pan and the heat went up and cooked in minutes.  When I used it the third time, again using the same pan, I again selected "sear", but it would not get more than warm.  I tried moving the pan, and re-adjusting the heat.  It would not get hot, at all.  I returned the product.  I have had other Fagor items and have been very pleased.  I am hoping this is not an indication of poor quality all around.
