Beware before Buying Hawkins cooker New series. Review on Hawkins Normal Pressure Cooker

I would like to inform that recently Hawkins has updated there pressure cooker saying new improved series, but totally it seems all in vain, pls read the instructions manual clearly before buying, i repeat,the company has modified and designed new vent &weight in their pressure cooker which is a totally disaster, it is not like the old pressure cookers who used to whistle loud  without continuation and one can do their other house work by counting whistles for rice potato dal extra, the concept now has changed the whistle is low and comes in jerks short term factor, when you call customer care or distributors they try to explain the new mechanism they have introduced regarding fast cooking time and saving energy gas etc but all in vain and waste of money.

I am writing this because I sell pressure cookers and often have a debate with customers regarding this matter but at last I have to refund the money because the customer is always right plus no proper response from distributors and concerned authority.
