That tray looks awfully small, but I guess it's fine if it's cooking for 1-2 persons.

I have been using a Vees airfryer for nearly 2 years now (back when they were still gadgets and thus expensive) and I can say it's worth it. Roasting a whole 1.5kg chicken, grilling steak, frying chicken, fries and nuggets... Never used it for baking as the family don't really have a sweet tooth.

You should post pictures of the included recipe book (if any) so they can see how easy to use it.

An airfryer works faster.

I think you can actually turn your normal oven into an airfryer by adding a heat-resistant, high-speed fan inside the oven to mimic the air circulation of an airfryer.
