Bought this for my parents as well. They are using it fine without any complains of shock or any other kind. Only thing they mentioned that the roti's are a bit thicker than usual but that is ok. I guess a proper grounded wiring should not cause any issues of shock.
May be Khakra is the only thing you can make using this product. However that will need too much trial and error to be successful. Not sure where you are based. Try ready to eat Dadi's Khakras. These are good. Available in Bangalore. Not sure where you are based.
this is for chapati, but you need practice then only you can make. demo CD also available, now a days customers are use for bread, omelet, small dosa also, as the both side a heating plates, like hot tawa
