I agree. And that's partly why I didn't buy it. But it was tempting, at two of them for $5. They might be useful as a substitute for lemon wedges that would save on waste. Or if you added a little lemon or lime juice to a lot of drinks daily.
I got my new cheap air fryer today. Now I need to figure out how it works, and what I should use it to make. It's smallish at 2.5 quarts. Even so, the unit is larger than I expected.
