I recently bought a full used set (off of EBay for a good price) for my wife's Edge. I am very impressed with the front liners and rear cargo liner. I removed the fronts to clean them and the carpet did not need vacuumed at all.
I am not as impressed with the second row liner however. The front half of the floor in the second row of the Edge slopes downward towards the front seats, and the liner is flat and does not match the contour, so it also slopes downward. Sloping as it does, it is not deep enough at the front in my opinion, and can allow liquids to run over the front edge under the right circumstances. It does provide great protection to the sides and rear, but I feel that it could have been designed to better address the sloping floor.
Overall, I highly recommend the liners.
