The blind mechanism is very smooth and easy to use. Fairly attractive, seems to reduce heat as well. Great for small kids.My only minor quibbles are 1) the blinds don't seem to make it all the way to the bottom, and 2) the glass frame doesn't quite make it all the way to the bottom of the patio glass. You have to mount the blinds about an inch above the top of the patio glass to avoid hitting the glass as you screw in. As a result, there was a tiny 1/4 inch gap at the bottom where the glass blinds don't overlap with the patio glass. Not noticeable unless you get on your knees and check, so a minor quibble. My patio glass measured 79" in height, btw.
