Rating : - does the job
This isn't the sturdiest product I've ever used, but the price is right for what you get. The only real negative is the the two pieces that come in the box don't attach to each other and when mounted leave a slight seam. It's barely noticable unless you know it's there (which I do). Otherwise, great product, easy install.
