Air fryer works. One major complaint is the basket / drawer leaks steams as it cooks which leaves puddles on whatever surface you have the air fryer. If you press lightly on the basket / drawer the steam stops leaking out which means either the product wasn't designed well or manufacturing tolerances are poor. Even though it works, I wouldn't recommend as the mess it makes it just too annoying to keep cleaning up after every use.

After Cosori support saying that leaking steam from the basket is normal, I am reducing my overall rating to 1 star as this product is clearly made cheaply / poorly designed. Definitely DO NOT RECOMMEND buying from this manufacture and go with a competitor's product that doesn't leak steam and make a mess on your countertop.
