It's easy to disconnect /connect accessories when new. If you have hard water though, over time it can build up inside it and it's very difficult to press down to disconnect /connect.
My first order,same item, came short of one of the 2 ordered. My second order placed by me to replace the missing one arrived with one of them damaged/broken, straight out of the bubble wrapping. Either they are extremely poor quality, and/our Sears dumped a broken one on me.
