I've used my new Brita filter for the last few months.  I particularly loved the extra capacity, but was disappointed to find that the compartment above the filter does not have the same capacity as the jug, so it needs to be filled twice to fill the jug.
Secondly, if the jug is inadvertently overfilled, the water dribbles down the handle, and leaves a puddle on the counter.
I really do love the jug and filter though.
