Good brush
Brushed with a regular comb and slicker brush yesterday, Furminator today. Still removed about 3 times more fur today. It also doesnt leave loose hairs on the coat like other brushes did. Dog fell asleep while brushing, which he never does, so I think he liked it. :)
The only downside is that the button seems pretty flimsy. The third time I tried it, it got kind of stuck. Managed to get it back, but dont dare to use it now. Actually easier to just pull the fur off with fingers though.
