I was a bit scared about ordering this product after reading some reviews stating smaller or larger to ensure the mounting difficulties. In fact, if you follow well the explanations with the help of sketches there is no difficulty and installation is almost childish. Now remains to be seen to use a flat for a product as prescribed by the manufacturer should not be used beyond 5 years from the date of manufacture, the one that was delivered is old one year built since December 2012.
