I found it easy to order on the site. My order came very promptly - maybe 3-5 days after ordering. But when my repair man came, he showed me that some of the ridges on the cartridge were either missing or broken. I told him that I would return it, but he said that he would be able to make it work. It works, and my faucet is not leaking, but I sure hope that it lasts me for a while.
