The filter is great. It runs without problems, air is quickly out and the filtering performance is enormous. The hose connection can be very easily removed without application of force and a wet AQ cabinet. The only drawback is that the self-priming did not work for me despite dry Vorfiltergefäß and that has the self-priming and does not work for a cleaning (ie everything drawn with mouth :)) Otherwise strong buy recommendation for all who need a reliable soft filter.
