We are following up the kaff service for my stove KH 60 BR 31 since past 6 months. They are not replacing the burners and the burner is generating yellow flames since past 1 month. Every time you call they say either the stock is not available or they will come on Monday. After spending hell lot of money with the notion that it is good product made in Germany.blah blah.it turned out to be a traditional choolah. Never buy Kaff product.
