Mine loved the pee pad holder when I tried it. As soon as I was out of sight, they took to shredding the pad to pull it out of the holder
My friend put her pee pads in a litter box and that helped with the pee-off the pad.
It is so funny when you see their front paws on the pad, they pee off the pad, and then they look at you as if to say, "I am on the pad."
