Ordered two blinds after seeing the ones my brother had. They are great - they have solved a problem that we had with windows on our doors for years - we had net curtains on them that were just a pest, but after seeing these blinds we thought we would try them so bought one for the back door and one for the glass panel at the side of our front door - SUPERB is the only word to describe them. We have now fitted one to kitchen window and the bathroom window and again they are great. The only problem we encountered is that the depth between frame and glass on the normal Room windows is smaller than the minimum 18mm so we got around this by simply attaching foam fraught excluder on rear of frame before fitting. I cannot believe how simple they are to fit - slide brackets under the rubber seal and clip blinds on - all in it took 10mins max to assemble and fit blind on to the windows. We are now going to fit them on to the rest of the upstairs windows. Brilliant product 👍🏻
