Key Features
Pros & Cons
Pros
- Two drawers can run different functions, times and temperatures simultaneously, according to the manufacturer, so two dishes can finish together
- Six cooking functions cover frying, roasting, baking, reheating and dehydrating in one appliance
- Dishwasher-safe non-stick baskets, as stated in the product listing, may simplify cleaning
- Manufacturer-stated per-drawer capacity of up to 1.4kg of fries or a 2kg chicken suggests scope for family-sized portions
- Two-year guarantee upon registration extends manufacturer support beyond a standard one-year term
Cons
- The stated energy saving, fat reduction and cooking speed figures are manufacturer-conducted comparisons rather than independently verified results
- No independent testing was available to verify the capacity, cooking performance or durability claims
- The material is described only as plastic, with no further detail on build quality provided
- No noise level, weight or power consumption figures are included in the available specifications
Who Is It For?
Suitable For
- Households that regularly prepare two different dishes and want them ready at the same time
- Kitchens with counter space to accommodate a unit stated as 41.5cm wide and 32.5cm high
- Buyers wanting frying, roasting, baking, reheating and dehydrating combined in a single appliance
- Buyers content to rely on manufacturer-stated performance claims in the absence of independent test data
Avoid If
- Buyers who need independently verified energy-saving or fat-reduction figures before purchasing
- Kitchens with limited counter space, given the unit's stated 41.5cm width and 32.5cm height
- Buyers seeking detailed build-quality or material specification beyond a plastic construction
FoxVerdict
Score 97/100This suits households that routinely cook two different foods at once and want them ready together, such as a main and a side, given the two independently controllable drawers. Buyers who want independently verified energy, fat-reduction or cooking-speed figures rather than manufacturer-conducted comparisons should factor that gap into their decision before buying.
