## At a glance

- Four listed modes: Air Fry, Roast, Keep Warm and Recrisp.
- Two removable glass containers, listed as 1.4L and 3.8L, allow different portion sizes.
- Storage lids let the cooking containers double as leftover-storage bowls.
- The listing says the parts are dishwasher safe and describes the glass as thermal-shock resistant.

## Pros

- Two container sizes offer flexibility between personal portions and the larger listed 3.8L capacity.
- A portable power pod design may suit kitchens with limited counter space or student accommodation where a plug socket is available.
- The glass containers can be served from directly and covered for storage, reducing transfers between dishes.
- Customer feedback reports ease of use and cleaning, alongside positive impressions of compact size and cooking versatility.

## Cons

## Before you buy

- Listing details are inconsistent: the title and capacity field identify a 3.8L model, while configuration and feature text specify both 1.4L and 3.8L containers. The listed dimensions of 24.9D x 29.8W x 29.3H centimetres also differ from the included-kit text dimensions of H:34.5cm W:30.4cm D:34cm. Confirm the selected listing's container set and overall dimensions before purchase.

## A good fit for

- People wanting an air fryer with a removable glass cooking bowl and a smaller container option.
- Small kitchens or student houses where a portable, plug-in appliance and compact footprint are priorities.
- Buyers who value containers that can be used for cooking, serving and storing leftovers.

## Less suited to

- Households needing multiple cooking zones or simultaneous separate cooking, which is not listed for this model.
- Buyers who require one confirmed overall dimension, as the page gives conflicting measurements.

## Customer feedback

Customer feedback highlights ease of use and cleaning, compact size, versatility and cooking speed. Some customers describe quick cooking and favourable results with roast potatoes and chicken. These impressions may matter for buyers seeking a convenient everyday appliance, while the listed 3.8L larger bowl and 1.4L smaller bowl suit different portion needs. The positive feedback does not establish identical results in every kitchen or dish.
- Positive themes: Customers report that it is easy to use and clean.
- Positive themes: Feedback praises its compact size and versatility for different dishes.
- Positive themes: Customers describe quick cooking, including a report of roast potatoes taking half the time.
- Positive themes: Some customers say it offers good value compared with using an oven.
