Excellent design, well made. 
The only reason for 4 stars instead of 5 is that of the four showers in our house, it could only be used in one.  In one, the bottom reached down to the shower control knob and could not be fastened. In another the hose from the hand held shower interfered with the unit laying flat against the shower wall. The third has a spa system and could not accomadate the caddy.  Make sure you measure and visualize before ordering.
