Brita user for years, I had the old model with display of the wear of the filter. Each week, a filter bar was dying ... Useful to remember the filter change. This new model, very pretty good finish. The new display normally mention the actual wear via a "sensor". After some time, I realize that it works just like the old one bar a week ... so the sensor is of blah ... too bad for this price. That said, it's still a very good product. I kept the old model several years and I always use it at work ...
