Handy, easy to clean with a small defect

We have now changed over from the old system to the Britta Maxtra cartridges. The Fjord filter is stylish, easy to handaben and easy to clean. We especially like the fact that you no longer need to remove the lid for filling. The Maxtra cartridges keep really longer than the old ones. One point deduction is available for the incorrect functioning exchange display. This is only after 2 weeks back to a line, rather than after 1 week as described in the instructions. The overdue filter change is therefore appropriate only after 8 weeks, rather than after 4 weeks.
