From my Gorenje Hot Set two hobs have passed after about 3 months. The built-in cooker made no overall reliable impression on me and I had no interest in further defects, I have, after some research for an alternative built-in cooker, namely the Siemens EQ231EK02 (camp = 1638 & creative = 19454 & creativeASIN = B00FFDZRI2 & Linkcode = as2 & tag = delta0c-21 ) decided. Even after more than four months no sign of any defect in the Siemens stove to recognize.
