Households are ditching their traditional ovens in favour of a budget-friendly air fryer that is being hailed as a 'game changer' for family meals. Savvy shoppers have discovered a 'hidden gem' on Amazon that promises to cook a Sunday roast in half the time of a conventional oven.

The Keplin 9L Dual Zone Air Fryerhas become an overnight sensation, with fans claiming it rivals premium brands like Ninja but at a fraction of the price. Offering an impressive extra-large, 9-litre capacity, it offers 15% more space than standard dual fryers. Serving up more cooking space for less, this model currently has 29% off at Amazon, reduced from £64.88 to £46.02.

Air fryers are often touted as the ultimate kitchen weapon for those looking to slash electricity bills. According to Amazon, the Keplin model uses advanced 'Even Heating Technology' to cook meals approximately 50% faster than a conventional oven while reducing electricity consumption by up to 55%.

A great choice for making meals healthier, the air fryer claims to need up to 85% less oil, giving a golden crunch without the usual greasy cleanup. The two non-stick baskets make cooking entire meals a breeze, and clean up is quick with a gentle rinse and less scrubbing.

Easy to use, the appliance features a digital touch screen interface that allows for a quick start in under 10 seconds, offering intuitive control over the cooking process. For super straightforward cooking, it comes with six culinary presets - Air Fry, Bake, Roast, Dehydrate, Reheat, and Crisp - all of which can be customised for specific times and temperatures to suit various recipes.

For shoppers looking for a more compact option, the Keplin 4.5L Air Fryer is full price but also great value at £39.99, featuring the same technology and plenty of positive reviews.

Elsewhere at Debenhams, the Living and Home Dual Basket Air Fryer has been reduced by 49%, down from £120 to £61.60. With eight pre-programmed cooking modes and a unique viewing window with lighting, customers have called it "a good product for a great price in the sale."

For buyers with deeper pockets, the industry-leading Ninja Foodi Dual Zone Air Fryer has £50 off at Ninja Kitchen. Reduced from £199 to £149 for a limited time, the Foodi has a 7.6 litre capacity and six cooking functions.

Amazon shoppers who have already snapped up the Keplin 9L Dual Zone Air Fryer have given it an impressive 4.5 out of five-star rating. One shopper said: "Brilliant. Don't be fooled by the low price, this air fryer is exceptional.

"It has two large drawers, I actually roasted a whole chicken in one of them. It's easy to use and does a very good job. I wholeheartedly recommend it."

Another added: "It's far quicker than using the oven, which is a real bonus when I'm cooking for myself and my partner after work. The two baskets are brilliant, you can cook two things at once without flavours mingling, which makes preparing a small roast for two much easier than I expected."

A third was delighted by the product, saying: "One of the standout features is its energy efficiency. This air fryer cooks meals 50% faster than a traditional oven, which has noticeably reduced my energy bills. It's perfect for quick dinners or busy nights."

Some buyers were less impressed, however, with one noting: "The product is worth it for the price, but takes a longer time for fries compared to the product we had before."

Most buyers seem to be impressed, especially with the 29% discount. Another happy buyer enthused: "Cooks potatoes, fries and chicken just wonderfully. Got in on sale and had it for a few months now and don't regret it one bit. Did I mention it's huge and can handle a lot of food in one go just fine."

Another added: "Don't spend hundreds on a brand name like Ninja, this bad boy does exactly the same thing and having used it daily for the last month or so I've been very happy with it. Great size too. Well worth the money and easy to use too."
