does not grip all shower floor surfaces [SEP] the general design is fine i did not find it super easy to use but that is because it would not grip to the floor of my shower which slip resistant and has a finely textured surface the little suction cups will not stick to it so i have to step on one wing to hold it in place try and scrub my foot and then reverse the process my shower walls are smooth so i stuck it to the wall but periodically it lets go and crashes to the floor if i knew what i know know i would not have ordered it because it does not work well in my shower
