Roti Makers have never worked so far I have used it. It just works in advertisement that you watch before buying. Its totally fake. A Hostel living person away from would always love this product after he sees on advertisement but trust me you will just waste your time and money and it never gonna make a Roti for you.You cannot even have a rounded shape Roti with such machines. Whether you buy Roti Maker of Philips company or of some local company its never going to make a Roti for you.So, my only suggestion for you is not to buy such products.Its totally waste of time.
