I was skeptical at first. I have tried so many grooming brushes for my dog and none of them have truly worked. I have a 5 year old rescue Winston who is a chow, shepherd, lab mix. Lots and lots of hair!
I honestly couldn't find any cons with this one but lots of pros. Glides through his hair quick and painlessly. It is so very easy to get the hit out of the brush. You literally just push the button, it slides the base to the top and you just grab the hair and toss it!
