Its OK for the money - if you can get one for under £130.
The base model only has a pitifully short hose though, so you might want to condsider a higher model in the range if you want a longer hose.
I got the Air3 Agile from Currys last year, when they first came out - I''ve used it a fair bit and apart from the hose, and its poor connection to the tools and the wand which forever keeps falling off, Its OK as just an upright cleaner. Its very light and not too noisy. As with anything from Vax - its hit and miss whether you will get a perfect one though, or one with manufacturing defects.
