Bests & Worsts Reviews from Amazon

At first, this product worked well. However, after a few months, the lid began to malfunction. The pressure value no longer floated up correctly. Thus the pressure cooking feature became useless and my food began to leave a burned residue on the bottom of the pot. I have contacted the Instant Pot customer service department twelve days ago, but have not received an answer or resolution to this problem. It seems to me that the Instant Pot should last and continue to function well more than a mere three months.
