Easy to install. The instructions were accurate. Works as intended. Complete sentence. better than trying to build your own and much more user friendly. Some people say they can just cut a piece of sheet metal into the shape they want, then drill holes and attach screws. It may technically work, but it is a high quality, professional and durable product. costs money.
