I buy it because of the reviews I saw ... that was almost all unanimous about the effectiveness of this brush, I have a little red cat about 3 kg, and of constantly losing hair, but unlike d Other brushes, more claissques, sui hurt the cats, this one my cat appreciates because she felt I caress in this way, without forcing, and that although the death ote hair above but below , it's amazing all that in 10 minutes enelve brushing ... this does not emepche losing his hair, but less anyway, I guess if you really did twice a week, that must really be effective, I must do that every 15 days ... but on the other products, excellent quality, clever, good grip of the handle, and it does no harm to the cat. on the contrary .... I highly recommend.
