Prestige Aluminium Rise & Time Pressure Cooker

I have had my prestige rise and time pressure cookers since 1987 and it is still working. I have had no problem getting spare parts for it over the years. it does not work as efficiently (timer doesnt work)as it used to but I can still use it and, infact I cooked a pot roast in it this morning. I would reccomend this product to anyone real value for money.
