I love the Brilliant Pad and having the renewal pads sent ever 4 months is great. This whole system is a game changer. I have a chihuahua and in the summer my dad and daughter being there chihuahuas. The changing of wee wee pads was a burden. The house smelled bad too. But now not a problem. They use the pad and it rooks up and no headaches or smell. Best investment ever!!!!
