Works rather well. Does have some design flaws. Like where the first mat starts. All paydirt rushes into a wall wich starts clogging easily. So a small added ramp would fix this making sure all dirt goes over the mesh. Fixations screws on the fold are somewhat difficult to fasten securely, making the sluice fold while running it and loosing material.
But overal a fair product for a fair price!
