I am satistfied with the quality of the cooker and the design it has. I think for 2 people 3 liter cooker is a enough. Cooker saves our energy and time. It saves fuel and money as well.This cooker is made of high quality aluminum and is of 3 litres so I can use it to cook several things at once. It’s Gas compaitable, Long lasting gasket, anti bulging base and ISI marked.Material: Aluminium.It’s service good. now lets talk about features of this pressure cooker. if u buy this cooker then see the wistle of this cooker had very nice shape.
