Title: Totally dysfunctional
Review: The new PUR click-on device won't stay on the faucet, rendering it totally useless. My faucet has threads on the outside and the attachment used to secure the device to the faucet blows off as soon as you turn on the water. It may work with faucets with threads on the inside, but all I know is it won't stay on my faucet. PUR is aware of this problem and the company promptly sent me what they said was a newer model free of charge. However, it app[eared to be identical to the the one it replaced and has the identical problem. Now I have two PUR faucet systemsPUR 3-Stage Horizontal Faucet Mount Stainless Steel FM-9100BI can't use. I gave it a one-star rating, but it really deserves a zero.
