Although placing the order was a simple experience, the logistics on the installation date was awful. I had the installation cancelled 4 times and this was generally either cancelled the evening before the installation date or else was cancelled on the day of installation. I had taken days leave for each of the "arranged" installation dates. However when the engineer did turn up, and he was on time, the installation was simple and he took time to show me how it all worked. Get the logistics of the installation dates sorted and it will be a 5 star rating, however this did let the score down so I gave a 2 star.
