the width was fine but the length was way too long, by about 25mm, the bottom weight and one slat were hanging over the edge of the lower window frame, double checked my measurements as i used a blind fitting comany and they confirmed my measurements were good and the blinds were too long, I'm now in the process trying to get it sorted out via their customers services dept, as i have to somehow prove it was their error and not mine, it might require an legal affidavit from my fitter, also it's going to be a big hassle having to post it back to them, luckily i only ordered one initially as i wanted to check on the quality of measurements before ordering the remaining six other windows, good job i did otherwise i would have had to return all seven blinds, its the first time i have used blinds to go and so far I'm very disappointed, i wouldn't recommend them as their quality control is very poor.
