Review of Color Blinds

we have had very bad experience with the workmanship and installation of our blinds last year. One blind was broken before it got installed and the controls were on the wrong side. The measurement of one blind was not taken correctly.Result: it was too short.The guys who installed the blinds did not have a clue what they were doing: wanted to drill a whole into the metal frame of our sliding door... to have the controls fixed. On another blind they drilled the holes at the wrong height two times and then did not even have the decency to fill and fix the holes properly. No discount was granted - we cannot recommended Color Blinds at all!!!!!
