I put this in the office sink to hold a scrubby and a dish wand that was always dripping soapy water onto the counter. Or sometimes people put it in the jar I provided upside down, and all the soap would leak through the sponge. This caddy solved both problems. It has stayed stuck for three days in a high volume kitchen (over 50 people on my floor). I've also used this at home and it has stayed on for over a month now in a sink that is almost always full of dishes from my 5-member family. It is a bit tricky to click the rack into the hooks (I though it only rested on top at first), but then I forced it in and it does indeed click in. I love how the scrubbies and wands now drip into the sink instead of all over the counter!! Makes it look more tidy too. Customer Service is also excellent, as I received an email from the seller offering to be of assistance if I had any problems with their product.
