Bought two for the guest room. Installation was a bit tricky (the head rail wouldn't fit into the bracket easily), but once in, they shades seem to be secure. One of the shades would not stay down, and would continually creep up. Now, several weeks later, both shades work as expected. The one drawback....the head rails are open and the shade mechanisms are exposed. My concern is for the collection of dust over time. Guess if I got up there to regularly vacuum....? They do provide good room darkening, however.
