I had Phillips air fryer. I find it cooks like a mini oven. I can get food cook with pretty much same result using a oven.
I have a full size electric oven but the problem with ovens is that if you don't use them regularly they eventually develop problems e.g. the oven door locks up, they trip the fuse of the whole house,.. This warning was provided by an experienced sales person.
So if I want to use my old oven I will have to get it serviced :(
I'm looking at the smaller airfryer as an oven replacement. Only need one to bake small quantities of fish. The smaller airfyer will also do it more efficiently, using less power then a full sized oven.
