This is a great product brought it for my nans at xmas they both love it. I know it has been cheaper in the past but best price i can find at the moment. This one is the green version. This is the culinare one there are some cheaper makes around which have poorer performance eg batteries running out quickly or not cutting all the way round the tin.
£20.93 at chemist direst but lots of reviews on there.
