we have purchased jumbo kitchen king (40) on 18/11/2009. while cooking on the second day itself we have seen small bubbles on the corners of the heat plate.Next day again while cooking we observed that the layer of some bubbles has gone .We stopped cooking as the small particles of that coating is mixing with the food particles. Immediately we have given the complaint against it through phone, they said they will replace it, we have seen upto now but there is no response from them.So consider our complaint and respond as soon as possible.
