I’ve been eye-balling these gizmos for the past year or so and am still not convinced they are worth either the price or the shelf space. And are they a total pain to clean? I mean, I like the idea (a lot!) that you can get nice crispy food without using lots of oil, but it almost seems like they are too good to be true. Also, why are they all so bulky and shiny black and ugly? Quite liked the look of this one in El Corte Inglés today. Anyhow, any advice?
