I bought this secondhand on Ebay but unfortunately it was damaged during delivery (as you can see in the photo). The outside casing has been cracked and there is a hole in the plastic top. This appears to be separate from the metal heating chamber inside. I have not tried using it myself, I have never had an air fryer before so I do not know if this is only cosmetic damage or not.
If someone knows more and thinks it is safe to use, then I would behappy to let you have it.
The full model details are: Ninja Air Fryer PRO 4.7L, Single Drawer, 4-in-1, Air Fry Black AF140UK
Ninja Air Fryer PRO 4.7L with a broken case (Temple Fortune NW11)
