What types of coat problems does this comb address?

The comb is listed as removing loose hair, eliminating tangles, breaking up knots, clearing dander, and lifting trapped dirt. These five functions are all stated in the specification, making it a general-purpose coat maintenance tool rather than a single-purpose brush.

What is the comb made of?

The teeth are stainless steel and the handle is plastic. Stainless steel teeth resist rust and bending better than plated or coated alternatives, which matters when the comb is regularly exposed to water from baths or damp coats.

Is the handle comfortable to hold during longer grooming sessions?

The listing describes a comfortable handle, and the plastic construction keeps the overall weight low. The stainless steel teeth are noted as being gentle on the pet's skin, meaning grooming sessions are described as a pleasurable experience for both the owner and the animal.
