The innovation lies in the digital display of the cutting length. Be careful not to confuse mm centimeters because it will result in a very short haircut. I can testify.
Regarding the hoof, I always encounter the same problem, hair crammed between the blades and the hoof and it must constantly remove to remove the blades otherwise not want to know. Each time, I find that unfortunate.
Without this, the blades are extremely effective and there are not too small long hair lying around even in a single pass.
