Query: Do not buy. Does not absorb pee.

My dog peed on right in the middle of this pad and when I went to throw it away, there was a giant wet spot under it. Luckily I had a plastic puppy blanket underneath. The good reviews for this product are from years ago. Obviously something has changed since then. I have only used one other brand of puppy pads, Four Paws Wee Wee pads, and have not had this problem before. Guess I should've stuck with the more expensive kind that actually works.
