Hi Sense Airfryer

In August I bought a HiSense Airfryer on line from Everyshop. A few months later I noticed that food was taking a long time to cook. I used my oven thermometer and the temperature was 150 instead of 200. I sent an email to Everyshop and the Airfryer was collected the next day. They have now had it since 29th November. When I phone I am told it is at the supplier. Don’t buy a Hi Sense Air Fryer, especially from Everyshop.
