With 4500+ verified purchase reviews and 4.7 stars of average score at Amazon.com, I really have high hopes on this one.
But upon my trial, it was a complete disappointment and my only conclusion is that these people must have not tried Furminator in their lives! I attached a few comparison pictures, the victim is my beloved tabby cat (also as attached). I had a few more pass with this "self cleaning" brush than my Furminator actually and the result was quite obvious: it doesn't even come close to the amount of loose hair that Furminator can pull off (I did Furminator after Hertzko).
I'm glad I got this as a gift so I didn't spend a penny on it (though technically I probably could have other gift for my Thanksgiving instead).
