one side works but that is all i need [SEP] i like one side of this silicone back scrubber from lnlofen the soft brush side the one with the longer bristles works great for scrubbing my back i can actually feel the bristles move against my skin and so i feel like i m getting cleanthe other side the stiff brush side just slid right over my skin i didn t feel the bumps at alli m and slender the back scrubber is long enough for methe package includes a hook to hang the brush in the shower but i just loop it over the shower rail and it dries quickly the brush can roll up into a compact bundle for storage
