GBBO Opera Cake Kit 2 "Opera cake kit skew." Carolyn Knight 25 November 2016 This is for the experienced cook. I was so disappointed that there were no diagrams or better still an educational video for the use of the equipment. I had assumed a true rectangle which I had hoped to use as a template cut-out for other purposes such as making a gingerbread house but the angles were not square which would result in a skewed rectangle! No use in the house building! But perhaps I was expecting too much. The frames were well constructed to be fair. If you won't mind the slight skew distortion of the rectangle would be useful. Sadly not for me. A note from the team We're sorry to hear you've been disappointed with this product and can understand your frustrations. Some instruction booklets use diagrams rather than clear text and can be a little confusing, especially if not showing the angle that you've decided to view your creation from! However there's no excuse for a poorly constructed house that's been let down by it's foundations.We hope you were not too disheartened.
