Query: sleek design, poorly constructed

We recently bought the newly designed PUR system for our kitchen sink.It looks really nice and fit easily to our sink but we have replaced it twice within three months because it randomly fell off and couldn't fit back into place.The entire weight of the filter is resting on a tiny piece of plastic that doesn't hold up well.I was hoping the second one would work so it was just a "fluke" but we're done with Pur for now!
