Excellent product, and easy to fit. Mine has been on for 4 years now without any problems. Since then I have fitted one for my father-in-law, one for my son, and one for a friend of my sister in-law. (with no discount offered, even though I asked!) The issue is it takes so long to get one. All the ones we have had have been standard sizes in white. They either don't seem to carry ready manufactured standard size white stock, or more likely they are using the manufacturing delay reason to optimise their transport routes, which, when it costs £65 delivery, I could probably get a separate company to do it for that on next day.
