The ADB Petite does the brushing for you. (So saves your hands!)

It makes about 500 brushstrokes per minute. (So saves time and effort).

It has a safetychip that stops the brush whenever it feels too much pulling and the rounded flexible pins on the rotating belt cannot hurt the skin because of the housing to ensure gentle brushing. (So you can also brush dogs with it who hate to be brushed) 

Brushes very thoroughly so removes loose hair before mats can form. Will save you $100+ extra per year for dematting services at the groomingsalon.
