I initially ordered two Pro Pressure Cookers. Gave one as gift, kept. Mine quit working and was replaced with and PPC XL. The cooker never counted down, steam came out the pressure release valve . I checked the parts, called CS, they sent a new lid. This one did same thing, called CS, they sent a different lid that did not shut properly, did not count down, but had less steam outpouring then the others. Called again, they sent another and same issue, then called and asked for a Manager FROM AMERICA. Was sent to a supervisor out of country. She sent a 4th lid and same issue. It has the parts in the proper place, does not count down, and does not hold the steam. I am familiar with pressure cookers and understand how they work. This is not user ERROR. I sent an email with pics to the home office, no response. I called CS again. no help. I called Tristar in NJ, left a message, called again and got a corporate person who said she would have them call me. NO call received. I have taken videos of all the lids, the attempt of trying to get them to work, video of the steam etc. I read BBB and other sites that shows I am not the only one with a product that is NOT WORKING. Also a company that is hard to reach, a help desk that cannot help, and poor customer service. i WANT A FULL REFUND OR A NEW UNIT, THAT HAS BEEN TRIED AND TESTED AND NOT A REFURBISHED UNIT. THIS UNIT IS SOLD AT A COMPANY I WORK FOR AND WE DO DEMONSTRATIONS ON PRODUCT AND FOOD. i WILL INFORM THEM OF THE POOR QUALITY AND CUSTOMER SERVICE IF THIS IS NOT RECTIFIED.
