I am very happy Tray washing head, especially the depth of the tank! One good thing also for the silicone insert that protects the neck! The drain hose is long, so practice. I have not ordered the shower and more, I use that of the bathroom (shower) that suits me too. Installation is very simple, no complaints. I ordered this product to make it more comfortable the "drudgery" of washing hair, a disabled person. And that changes his life. I recommend this product again!
