I have been using a Prestige induction cooker for the last few months. I found it as a nice machine with a lot of convenience. Even children can manage it and it is power saving and fast in cooking.
One month ago it started malfunctioning with something like a timer problem. It would display an error "E 7" and the cooker turned off automatically.
When I disconnected the power and turned it on again, It would work exactly for one minute and turned off again. This problem continued for some days.
Anyway, now it has got corrected somehow and works well with only rare error displays. Now we use it as a remedy for gas shortage and use it for all kinds of cooking.
