These brushes have silicone bristles with a plastic back with a silicone plug. You pull the plug on the back, fill them up with shampoo, then go to town on your pet. You have to press the plug to dispense the shampoo. One of these has thick round bristles. The other has long slender bristles. Since the bristles are silicone, they do a pretty good job of grabbing loose fur while you're scrubbing your fluffy. They do seem to help get the shampoo deeper into the fur than you would with just your hand.
I tried this pet grooming bath massage brush, and it's okay. The silicone bristles are soft, and the soap dispenser is convenient, but I didn't notice a significant difference in my pet's grooming experience
