I have ordered Perfect Fit Roller blinds. I spent over £300 on the blinds for two windows. I measured everything as was per instructions. I also paid an additional insurance fee in case my measurements were wrong. However when the blinds arrived, the brackets turned out to be too small for my frames. My frames are quite standard. I spend a really long time emailing back and forth, and eventually they send me bigger brackets. I had to pay for shipping for the brackets. The brackets didn't work either. Even though I paid for incorrect measures insurance, apparently I am not eligible for any refund. They were also unable to provide me with brackets fitting my windows. I have wasted £300 and I have to chuck out the blinds. I do not recommend using this company for blinds. The blinds themselves are also not fitting the window - even with correct brackets I would have needed to re-order the size (even though I measured everything as per instructions). Their instructions lead to smaller measurements for the blinds than needed. Re-ordering mean also so much time wasted in negotiating with their support service, waiting for the blinds, trying to install them, etc. It's been nearly 2 months to figure out that the blinds are a complete waste.
