This support for dry hair is really very cheap in comparison with another product. Without drilling, there arises the wall (of a tile or a very smooth surface) with a suction cup using a vacuum air system by screws. It supports a weight of about 3 kg, which is more than enough for a hair dryer! There is a location on one side to the electrical cord and the other for a brush. Everything is good and I'm delighted with my purchase.
