My family had bought Hawkins 10 Liter Cooker 8 years ago. Its stainless steel is of best quality. Since we bought we daily use it roughly. it still is in good quality. The food prepared saves lot of gas energy . it saves much time for many hard raw food items. I recommend to household persons to go for it as it is the best cooker. its all parts are easily available in market. Most importantly though, stainless steel is a safe option when it comes to use with food and beverage, as there are no chemicals that can migrate into your food from these products. Please save energy, Time & Nutrients by using pressure cooker. For large family food preparation just blindly go for it.
