Good product, but don't make the mistake I made
This would have been perfect, but I failed to read the directions that said to press the button to lower the brush, and brush the dogs fur first.  I didn't press that button, and the dog got just the powerful suction from my vacuum cleaner.  It frightened her, and now I have to start over getting her used to the vacuum.  Otherwise, this attachment was perfect.  Gave it 4 stars only because people tend to read the comments of those review....and, I wanted to emphasize that the product was good.  My bad.
Rating: 4 stars
