works well but for how long [SEP] i wanted a fairly stiff brush to rid my back of itchy dead skin this brush is great for that it is nice and stiff and i have not had any trouble with the head coming off unexpectedly nor have i figured out how to detach it but i have not needed to either the problem the bristles are not attached securely enough within two days of my getting the brush two or three holes worth of bristles had come out now there are four empty holes i have not been unduly rough with the brush in fact the bristles in one hole came loose as far as i can tell when no one was using the brush and it was just hanging from the showers door handle so i like the product but i do not know how long it will last
