Now a days we can see many types of Pressure Cooker in market with many Brand. It is difficult to find a good pressure cooker. You can go for a Brand.
First choose only steel body pressure cooker, dont go for Almunium body type.
Almunium is harmful for health, so avoid these type pressure cooker.
You can buy steel body pressure cooker, which is available with induction bottom. It can use with induction cooktop and gas stove both.
Steel body type pressure cooker expensive than Aluminium, but it is better. Steel body type pressure cooker has long life and durable.
So I recommend that only buy steel body. You can go for Hawkins, Prestige, United. Good luck.
