5lt Mellerware pressure cooker from takealot is a big no for me

5lt Mellerware pressure cooker from takealot is giving me grey hair. I bought the product in December 2021 then 11 months later it gives an E4 sign. I informed takealot then it worked again and I cancelled the return that I had logged. 15 months later after purchase I tried to use and it didn't work. Guess what I have to pay for repairs because it's out of the 1year warranty. I returned it last month and in 3days it's going to be a whole month since it was returned. I honestly feel like it's a waste of my hard earned R1000. I should have gone for other brands. I'm even sceptical if this product will last me a good 5 years. In future I'm staying away from mellerware products!
