When I got the glazing it was as expected and seems to have made a difference. I had to wait a while for different panes and then even longer for the tape which meant I had boxes sitting in my hallway for ages. In the end I filled in a form and got a very unhelpful response, luckily by the time they replied I found a well hidden phone number and arranged a next day delivery of the tape. The smaller windows look good, the window with the extreme tape doesn’t look brilliant as the tape came away a bit on application but it does the job and is good value.
