I had been finding suppliers who could customise my roller blinds as I wanted them to be, but couldn't find EXCEPT Blinds Downunder.
Alan has been superb with us from scratch till the finished product on our windows. A very generous, humble and professional person and everyone who is reading this review must give a chance to BD.
I gave measurements to BD, and being an engineer I wanted to have my products as per measurements. BD successfully manufactured my blinds with less than a millimeter tolerance, which is just awesome I would say. All blinds are a perfect fit (face fit) on my windows.

Approximate cost: $1500
