The button on the handle that shuts off the water flow works and is easier to press than the original. I doubt it will get stuck in the stowed position like the old one did as it got older. The hose is now more flexible which means less tension in use, it will curl up and fit into storage exactly as it should. The old nibs fit perfectly on the pen. It is easy to install with a Phillips screwdriver. I'm so glad I didn't have to buy a brand new device!
