The Ninja Double Stack air fryer, model SL400UK, is now available for £169.99 on Amazon as part of a Prime member exclusive deal. This represents a £60 saving compared to the standard retail price of £229.99, making it a compelling offer for those looking to upgrade their kitchen appliances.
Key Features of the Ninja Double Stack Air Fryer
The SL400UK boasts a total capacity of 9.5 litres, split across two independent drawers. Each drawer can hold up to 4.75 litres, allowing users to cook two different dishes simultaneously at different temperatures and times. This flexibility is ideal for preparing complete meals without the need for multiple appliances.
The air fryer also features six cooking functions: air fry, air roast, reheat, dehydrate, max crisp, and bake. The "max crisp" function uses superheated air to achieve extra crispy results, while the dehydrate function is perfect for making dried fruits or jerky.
How to Get the Deal
To secure the discounted price, shoppers must be Amazon Prime members. Non-members can sign up for a free 30-day trial to access the deal. Once logged in, the price should automatically reflect the Prime discount at checkout. The deal is part of Amazon's ongoing promotions, but stock may be limited.
Comparison to Other Models
The Ninja Double Stack is positioned as a premium model in Ninja's air fryer lineup. Compared to the single-drawer Ninja Air Fryer Max (which typically costs around £99), the Double Stack offers greater capacity and dual-zone cooking. It also competes with the Ninja Foodi Dual Zone, which has a similar dual-drawer design but slightly different features.
According to customer reviews on Amazon, the Double Stack scores an average of 4.7 out of 5 stars, with users praising its ease of use, consistent cooking results, and space-saving vertical design. Some note that the drawers are not dishwasher safe, but the non-stick coating makes hand washing straightforward.
Additional Considerations
The deal is exclusive to Amazon Prime, so those without a membership may need to weigh the cost of joining. At £169.99, the air fryer represents good value compared to the RRP, but it is still a significant investment. For those who frequently cook for families or meal prep, the extra capacity and dual-zone functionality could justify the price.
As with all time-limited deals, availability may vary. Shoppers are advised to check the listing regularly and act quickly to avoid missing out.
