An air fryer expert has issued a fresh overfilling warning to the millions of people who own the kitchen gadget.
And in doing so, he's also explained what he reckons is the perfect level when it comes to your air fryer's capacity.
Consumer experts at Which? regularly put the latest gadgets to the test so that the average British consumer can get a better idea of what they might be buying next time they need a new device such as a toaster, television, laptop, child car seat, or even sun cream.

At the core of that advice is a focus on the simple air fryer, which has quite simply boomed in popularity over the last decade.
In their latest video, Which? reveals five things you need to know before buying an air fryer. But if we're honest, it applies just as much to those that already have them, so make sure you pay attention.
In what is the latest piece of advice from Which?, it follows on from a list of five things you should never do when stacking a dishwasher - but not everybody is convinced.
And on the topic of air fryers, it is the latest piece of advice issued to the public, with previous warnings including flagging a common mistake that could cause your home to set on fire.
Money Saving Expert founder Martin Lewis has also got involved in the past, warning over a significant issue when it comes to cooking in your air fryer over your traditional oven.
And then there's a big issue with cooking particular foods in your air fryer, with a warning against it.
The overfilling warning from Which? comes down to what manufacturers are telling us as punters.
And according to the consumer experts, the advice they're giving is a little off. Up to 40 percent off in some cases, if we're being critical.
"Don't believe those internal volumes," so says Harry Kind a tech expert at Which?.
"Manufacturers like to claim that their air fryer has a capacity of 'x' number of litres. But who is measuring their food in litres?
"Instead, properly inspect the basket or cooking space. Overfilling will make food cook unevenly."
And what about getting that perfect fill level? Laughlin says: "How many layers of chips can you reasonable get in?
"In our tests we usually find that the true capacity tends to be around 60 percent to 80 percent of the claimed maximum."
Laughlin and Which? also advise to spend at least £50 on your air fryer so you know you're getting something that 'doesn't feel flimsy'.
And at the same time, we need to be honest in knowing that air fryers might save you a few quid over the years, it'll take a long time for you to break even.
