The door is actually fully detachable so that you can access any dirt, grease or buildup that might accumulate in the hinge, and all the trays and racks are removable.

The small silicone mitts are handy, although they could be a little thicker; they didn’t allow me to hold hot items for very long. At 382 x 324 x 339mm, it’s a fairly average size for an air fryer – albeit at the larger end – and it has quite a boxy shape.

For two large potatoes, you use one tablespoon of oil, which when compared to deep frying is a pretty good result. The charring in my image is a result of the harissa paste, but I've also used the Tower Vortex for a regular Sunday roast chicken and it did a spectacular job of a simple, un-flavoured chicken for this too. If you've got the space in your kitchen and need a seriously large air fryer, the Tower Vortex is a top choice. The oil-drip tray is useful for gathering any excess oils through the cooking process, and was very easy to clean.

There’s an auto function for chips that you can easily select from the digital controls to get you going, and with a fairly intuitive interface, we were off to a quick start. It will definitely makes its presence known on your countertop, particularly since it requires at least 10cm of free space on the back, sides and top. Since I normally have to use more oil to cook the cobs in the frying pan, having to constantly rotate them, this was both an easier and healthier way to prepare them. The air fryer monitors the internal temperature and cooks steak just to your taste, from a juicy medium-rare to a deliciously charred well done.

While this wasn’t the fastest result, I did go for the maximum amount of chips suggested by the manual and initially skimped on the oil.

The touch buttons produce a beeping sound when pressed, which can become annoying when you’re having to select a much longer cooking time (the default is 15 minutes). The catch is that it has to be a relatively small chicken – but even so, it would still be a big enough bird to feed a family of four. My fries came out well, but not as well as they come out when I cook them in my Ninja Dual Zone air fryer.

Holding down your finger works somewhat to avoiding the beeps, but it takes the appliance a good few seconds to figure out what’s going on. So if that’s predominantly what you want an air fryer for, we’d suggest coughing up a bit more for a premium model such as the Ninja Foodi Dual Zone. The air fryer’s overall noise level will depend on the temperature selected, but in general there will be some sound because of the need for the internal fan to distribute hot air. What’s more, it has a fully automatic rotisserie function, a feature we’ve yet to see from any other brand.

Due to this, we would strongly advise against pre-booking/making payment for third party trades to build/install your item until you are in receipt of and have inspected the goods. I put the Tower Vortex 5-in-1 Digital Air Fryer Oven to the test for a month, cooking up chips, fishcakes, and whole rotisserie chickens in the process. Next I tried the automatic programme for frozen fries/chips – which coincidentally comes with the same cooking time and temperature as the manual’s suggestion for homemade chips. Comes with a removable wire rack and cooking tray, with two different holding levels to reposition easily. It took a little scrubbing to remove stubborn parts, but for the most part it was a painless process.
