Query: So worth buying, it works just like the commercial.

If you are on the fence of buying this product, come on over. It delivers everything promised.I have a black lab mix, and I could never get any hair off of her from any brush, maybe a handful after an hour of brushing. I would always find her hair all over the house and I finally got fed up when I found it in some food I made. Gross!I came here and purchased the furminator and very glad I did. In one sitting I pulled more hair off of her than I did in her entire life. Her fur is extremely soft and shinny now, and plus no loose hair in my food anymore!This brush is worth the investment! Stop debating if you want to buy it or not. Amazon has the lowest price, believe me I shopped around forever, and no one compares to Amazon.
