These blinds were not a good buy at all and I am pretty sure it will not be long before they are discarded to the bin. Fitting the clips into the corners of the window seals was extremely difficult and the time taken to fit them was nothing like the 1:30 video clip. Trying to get the tension tight is near impossible and I have resolved to expect the blinds to be half open when they should be closed and half open when they should be shut. The plastic retaining clips for the chords are quite flimsy and it is only going to be a matter of time before they break. Buying these items was an expensive mistake.
