I am very Happy with this Shower caddy, it is very secure. The suction cups that are added for extra security actually work and help to hold the caddy in place. Love the fact that you can adjust the shelving to fit assorted size bottles and bath items. Great quality item, highly recommended item and company  simplehuman.  I also bought Tension Shower Caddy, Stainless Steel + Anodized Aluminum Tension Shower Caddy, By simplehuman very happy with it as well.
