Had this frying for about a year and it’s now virtually unusable. Was OK for about a month or so but now has completely lost it’s non stick. Have tried all recommendations e.g. using vegetable and not olive oil, not using too much heat but everything sticks and it’s almost impossible to clean. I bought it because I have Green Pan saucepans and have been very happy with them. However, this is the worst frying pan I have ever had and is now unusable. I am extremely disappointed and would not recommend,
