Bought 2 piviot roof windows and 2 blackout blinds. Windows look gd. One of them sounds like it has some grains of sand inside when tilting open then closed. U can hear it inside one side of the fame. The blinds are OK but don't completely keep out the light. I will need to add something to the inside of the fame for them to be completely blackout during the day time as I work nights. One of the blinds arrived with pretty poor build quality. The roller was disconnected where the pole meets the end piece. I manged to get this put together properly and for it to work. Overall the windows do look really good and manged to fit them myself. The blinds fit easy enough if they are built properly but I think they are massively overpriced considering it's just a roller blind with 2 channels down either side. Could probably make these with a little bit of trucking and get the same effect at a fraction of the cost.
