Query: Poorly designed, go with Culligan.

I had been using a Culligan faucet mount filter for several years. I decided that instead of buying another filter replacement for my Culligan I would try this PUR model instead. Big mistake! The attachment is for lack of a better word, junk. It is plastic and flimsy. I can't see it lasting more than a couple of months. The filter itself stopped working after only two weeks of minimal use. The next filter did the same thing. Mind you, my Culligan was cheaper, the attachment while sometimes difficult to screw on is secure, and the filters would last me close to two months. I only tried the PUR model because I thought that it might serve me better. Nope!!!!Don't waist your money. It might look nicer than the white Culligan model but the Culligan is a much better design. P&G; should take this PUR model off the market.
