I generally do not trust the dependability of products or companies that do business primarily online. But to my pleasant surprise Blindster delivered as advertised! I followed their instructions on measuring and also ordered samples of the material I wanted, to gauge the quality of the materials. The ordering of the items was very easy and organized on the site. Even after receiving the items i had doubts as to quality and how they would fit. To my pleasant surprise all fit perfectly to my measurements and the quality of the materials was very good as well. Also the blinds were very easy to install, just two mounting points and then snap the blinds in and lock down. I have the manual shades and the mechanism is very smooth and easy.
