content: Disappointing product from Delta. The return spring for the pump is rather weak and as a result you have to pump the soap out slowly as it takes it time to return to the start position. I was even tempted to pull the top up to help it along.Also, the threaded portion of the attachment mechanism is too short so what eventually happens when the bottle moves back and forth while being used is that is that it eventually undoes itself and falls off the mount.Delta generally makes solid products but this one is a dud.
