I am using this air fryer from last 4 weeks, this product is a waste of money and have many problems like the knobs do not have an indicator, I don't know what is the actual time set or what is the best temperature set.it does not have any markings on on the rotating knobs, also there is no instructions manual included which is too frustrating.I had checked the air fryer at my mom's place of same model and it has triangular on the mob to know what is the temperature and time setting. I don't have them on my air fryer so how to know which is time and which is temp settings.Therefore there are no complaints regarding the working of the fryer, but to use it is very frustrating and confusion as the settings are not able to understand.
