Tower Vortx 9L Dual Basket (T17088)

Tower's Vortx 9L gives you the most basket capacity for the money here, with two 4.5L baskets that between them cater for a larger family or batch cooking, a punchy 2600W rating, 10 one-touch presets and a Smart Finish function to coordinate both baskets, and Tower claims meaningful energy savings against a conventional oven. It ranks last because the savings show elsewhere: reviewers rate its crisping and build a step below the pricier Ninja, Cosori and Instant models. It is still the right buy if your priority is maximum basket capacity on the tightest budget (~£80) and you can live with a more basic finish; step up to the AF400 or Cosori if even crisping and a quieter, more solid build matter more to you than headline capacity.
