Steak stones customer service is really none existant, they will try to make you pay by bank transfer for the products as they know you will be back for a refund when you discover their oven is a pizza oven and not suitable for the heating of steak stones they sell. The steak stones oven heat Output is only 350oC, with a 30min timer. What you require is a longer timer in a working kitchen with minimum 90 min Mechanical timer and should heat to 450oC otherwise you will have a health and safety issue.
