Customer feedback highlights ease of use and cleaning, compact size, versatility and cooking speed. The feedback describes the fryer as handy for one or two people and reports positive experiences with foods such as roast potatoes and chicken. These perceptions fit the listed removable glass containers and multiple cooking functions, although the stated 3.8L and 1.4L container sizes suggest checking that portion capacity suits your needs. Aggregate ratings lean strongly positive, but they do not establish why individual customers rated it as they did.
