I ordered 2 sets of Perfect Fit blinds which arrived within the time scales advised by Tudor Blinds. Assembly of the blinds was straightforward and as shown on the video tutorial. I only watched the tutorial once and am pretty certain it said the brackets should be positioned 1 credit card's length from the each corner but I found the fixings meant I had to measure and calculate where to place the brackets. The blinds themselves are very good and make a very neat finish. The white slats aren't quite as white as the surround or I'd expect, so I'd recommend requesting samples before purchasing. All in all though I'm very happy.
