This is a shame - I have one of their combo air-fryers/pressure-cookers and although it is only a passable air-fryer, it is the best pressure cooker I have ever used and very good value for the relatively cheap price.
I tried their air fryer. Could not get rid of the toxic smell despite numerous, extended burn-in sessions, cooking in it, re-cleaning it, spraying oil in it, etc. Eventually gave up and got rid of it. It had great features but the smell was terrible.
