The ordering was easy.  The product arrived earlier than expected.  The courier left them on my porch since no one is home.  When I first saw the product, I was disappointed with the cover material since I have a previous one from another manufacturer in Germany using tight woven sisal mat.  However, unlike the previous unit that only one cat will use, this one both of our cats will use as scratcher and also play with the ball.  The unit is quite stable and the cats love to perch on top.  We were quite surprised but pleased.
