Mrsemmapee110 I have just a small compact airfryer - ideal for me alone, although last night did cook, easily and speedily two Chicken Kievs in it for daughter and myself last night (Sweet potato and potato mash on induction hob and frozen vegetables for us both in microwave)
Baked potatoes should be started off in Microwave and crisped up in airfryer. Chips - do not put in too many, and give them a good shake about halfway through cooking time.
If you really want to use this for cake making (I would not), then places like The Range, or Wilko have quite an assortment of different size baking dishes at very economical prices.
Would not try to store it anywhere other than on my worktop, so that it is quickly available for use. I do not find much heat coming from the top of this when in use, although I do tend to pull it forward when on, so it is not under the wall cabinets.
You do have to get used to it (like any new piece of kitchen equipment), so I use it for fish cakes, (ten minutes at 180), chicken legs (20 mins), ready made quiche (drawer is just big enough to take one of these supermarket ones) for 15 minutes. Small prepared quiche for one person will easily go in there for about ten minutes. I use a silicone insert in mine which helps to keep the drawer clean. This is just rinsed out in sink each time it is used. Frozen sweet potato chips take less than ten minutes, and normal frozen chips (I like large ones not french fries), about 15 minutes.
