Works as expected, but restricts flow a bit, but not enough to trigger the safety valve. I've used it to clean under and around a fridge I didn't want to take out, cleaned tons of cat hair and dust, didn't get clogged. mostly straightened. It also didn't fit my Kenmore Crossover Max's vacuum hose upright. I had to design and 3D print the matching adapter.
