Query: Don't buy this product!!!!

I bought the PUR Filter after years of using Brita products (pitcher and dispenser). It got annoying to have to refill them over and over, so I thought the faucet mount was an easy transition. God what a waste of money. After about 4 months of normal use, the mount would no longer stay on my faucet. It was constantly being knocked off and consequently would start spraying water everywhere. Before that, the light indicator stopped working even though the filter still worked. The faucet mount is flimsy and cheap, and definitely not worth the $40 or so dollars Proctor and Gamble charges. My fiance called Proctor and Gamble to complain and they sent us another one. Unfortunately we had bought a box of refill filters at costco, but once those are all used and finished this will be our first and LAST Pur product we buy.Buy Brita instead.
