So good that I bought one for my Mom. It's a great little Air Fryer.
Small Profile: It doesn't take over your countertops.
Easy to Use: The interface is intuitive with clearly labeled functions. It could be made even easier with a redesign, for example by adding a keypad for entering the time and temp, but it's still pretty darned easy.
Easy to Clean: I did some research on air fryers before purchasing one because I wanted to make sure it would be useful in real life. The bucket style design of this air fryer means that any mess from your cooking stays in the bucket. You never have to dig into the device with a toothbrush and a rag to try and extricate little bits and bobs from the innards. Most of the time, in fact, the non-stick bucket comes clean with just a rinse and a drop of soap. But, it's also dishwasher safe for those occasions when you'd rather let a machine do the work. This is huge, because a time saving device is unhelpful if the cleanup is hard. This air fryer is useful in real life.
Lightweight: I store mine on top of the fridge. It weighs very little so it's no problem to plunk it on the counter when it's time to cook, and then put it back when it's done.
Lots of Modes: It's versatile. You can do a lot more than frozen cheese sticks in this cooker. (Although cheese sticks are yummy.)
I highly recommend an air fryer in general, and this one in particular, if you do a lot of cooking for just yourself and maybe one other person. It's so great to cook up some fish and not spend half an hour cleaning out your pans and stove after dinner. It doesn't heat up the whole kitchen, it doesn't waste energy, and your food will be ready before most conventional ovens would even get up to temperature.
On really hot days when you don't want any heat in the house, you can take it out on your porch and plug it in there.
