Tissoli pots are ****

i have pot the Tissoli pots from pick n pay, and i started using them yesterday and it seems i have made the biggest mistake ever i should have just bought HART instead ,i cooked with this pots and all they do is burn my food after using my R1000 to buy them thinking i will enjoy them and the food. i am really disappointed and i should also this on social media platform to warn other users who would get attempted to buy them . they look fancy but when you cook they only burn the food
