I love the shades.  They are very nice.  The end cap kept popping off of one, but just needed to be reinserted.  Otherwise my only complaint was jumping through hoops to find install instructions on theorders page.  Did not come with any instructions and the video on the product page is for a completely different blind.  All in all they are pretty simple to install and are really nice.  If you have trouble with the mechanism being to hard to pull them you installed the brackets too close together.
