A good part, stainless steel, stainless, small and handy. But for my purposes rather suboptimal. The floor / horizontal drain is, and I wanted to use it to channel shrimp feed through a plastic tube with a 12mm internal diameter in dei food bowl. However, the small grains remain on the bottom of the hopper and horizontal rechtern would fall only by strong tilt in the process. But that's not because the funnel-downpipe almost there fills entire tube (the way it should be) and the Röhtre at the moment definitely not be tilted. Therefore, unfortunately only 4 stars.
