Would give it 6 stars if I could!
LOVE THIS. It's big enough that my cats can stretch themselves up to scratch it, and doesn't leave any shavings/fabric on the floor, unlike other scratching posts that I have.
I love that it's attached to the wall so it doesn't take up space. We rent our flat so couldn't drill a hole, but I used 4x heavy duty command strips (one per corner) to stick it to the wall safely and it doesn't budge, even if my cat puts her weight behind her scratches! Would definitely recommend this method :)
