These work wonders in my grooming station. They're very inexpensive ($6 from pet edge) They're amazing at working out matts and tangles. I recommend them to all of my clients as groomers know brushes don't always do the job and you will need a comb and know how to properly use a comb. They're built to last and I had to replace my first one after 6 years. I feel like that's a long time compared to some grooming tools.
