4-liter air fryer, Nikai brand. And the grill is electric, the plate is detachable for cleaning, and it has a bottom tray to collect fat. Both are working. I'm selling them together for 180, and one unit alone for 100. The grill's quality is amazing, and if I hadn't received the same grill as a gift, I wouldn't part with it. And for honesty's sake, I used the fryer a lot, but it has become small for the number of family members.
