My first Brita 3514 only worked well for about a month, then it started to leak, and the selector was difficult to turn. I did get to install a second filter and got perhaps half the life out of it before it didn't work at all. For some foolish reason I bought a second Brita, and am now throwing this out, it didn't last as long as the first one! The second one leaks through the filter release button and the base attached to the faucet.
