I used to have one too, 'til I gave it to my step-son.  He is still using it.  It seemed to be a little harder to pump than the PUR I now have, but they have pretty much changed the design of the whole thing since then, maybe that took care of that little problem.  Or maybe it was just me.  
I would buy another one in a heartbeat.  In face, since it purifies, and PUR no longer (as far as I know anyway) makes a purifying filter, I would buy it first...
