I ordered 9 of these top down bottom up shades and couldn't be happier. At first I was a little disappointed that there was a string for the top down part as I thought they were completely cordless - my fault I didn't read the description - but once I put them up - which was a snap - it was no big deal. I like to leave the tops down which is why I wanted these. So once I adjust the height of the top I only use the bottom anyway. They glide effortlessly. I paid twice as much for ones from ***** and they never worked right. I would defnitely buy these again.
