What works unexpectedly pleasant is the 2 in 1 idea. We had 2 airfryers, but always fiddling with times, and it takes up a lot of space. This device is no small boy, but certainly smaller than 2 normal airfryers, while the capacity is hardly less. In addition, the trays are more practically designed so that you get more and more shapes in them (at least we did). This makes it about 500% easier to clean and keep than the old skool airfryers. They are 2 airfryers in 1, so handy for preparing different things at once, but if you want to prepare a whole mountain of fries at once, you can also set the device as 1 which makes it actually larger than an airfryer XL. In addition, the device also works really well (because of other airfryers). Normally I rarely write a review, but this device deserves one, everyone who uses an airfryer deserves this device!
