I found a deal on these good through midnight tonight (23 hrs from now) and wondered if they are any good? Are they better than a regular brush for dealing with pet fur? Capn Morgan LOVES to be brushed and he has a very heavy coat, so I wondered if this would be useful. For just the cost of shipping ($4.99) I wondered if it would be worth trying on him. So if you have any experience with this, please let me know.
