Prestige cookers are good to use as well as long lasting.
Cooker quality is superb in case of material thickness.It can be used for 10 years or more. I am using 5 lit cooker since last 5 years, so I would recommend ladies to select prestige among branded.
So I would suggest to go for it as you will don't have to spend more money to repair that cooker in case of whistle or rubber ring for atleast 5 year as I am using it since 5 year.
