The new genie paws are great compared to the previous model. They have made them much larger & designed them with tons of rubber "nubs" to help seperate the cat's paws allowing the granules to be released on the mat instead of flying across the floor! The raised edges help keep the granules on the mat also. The mats are nice & easy to clean, in addition to being flexible so that you can pick the mat up, roll it slightly into a funnel, & dump the granules back into the bowl. However BEWARE! If you are one to stumble blindly into the bathroom at 2 AM & you accidentally step onto the mat barefoot, you will have a RUDE awakening! The nubs are killer on bare feet! All in all, I'm glad I bought one.
