Took about a month to be installed, which was about what I was expecting (and has beaten the arrival of the car, which has had manufacturing delays...). Did take several phone calls during the early stages though to clarify some questions and ensure the process was kept moving forwards. Installation itself was quick and done as tidily as you'd hope. [Regarding the "How did you communicate with the company?" The response only allows you to choose one response. I communicated with them by email _and_ by phone... Regarding the "How quick did the company reply to your queries? There's a massive gap in the options! - under an hour - 2-3 hours - 3-6 hours - 6-12 hours - over a week What if it was over 12 hours, but under a week?! In my case, email queries fell into that band, usually taking 24-48 hours to get a response. Phone responses were immediate.]
