Query: Works well!

I was surprised to see how well the Zoom Groom works. It pulls out the undercoat very well if you have a cat that will sit still long enough to be brushed. It is easier to group the hair around the ends of the Zoom Groom and then pull it off as a big mat and toss it. Make sure to have a vacuum nearby if needed. I am pleased with the product. I will have to buy another to brush my second cat's sides since she just wants to walk around and not stay still!
