Product review (1 stars): Bosch "stainless steel" knob that melt
I own a Bosch Gas cooktop NGM8054UC.  A knob melt while my wife was using a pan to steam some food.  Bosch really need to re-design the knob using completely different material.  I will post a picture of the melt knob.  My problem is apparently pretty common to other users.  I noticed that other users have exactly the same problem.  The US Government should look at the safety issue of Bosch cooktop.  The melting knob got so hot that you could not touch it.  It scared the heck out of my wife.  I was lucky to be at home and I had to turn off the gas supply and unplug the electrical power cord in order to turn off the stove.
