This brush works really well. My kitty is 23 years old. She doesn’t groom herself like she did when she was younger. And she has the softest fur that matts easily. Using this device makes her hair so soft and shiny. She looks like a new kitty! It’s very heavy so I have to be extra careful not to konk her in the head with it or press too hard. Wish I would have discovered it when she was younger. It’s so sturdy that I’m sure it would’ve lasted for 23 yrs and then many more!
