The coat king can break the coat rather than just pull out the dead fluff - it does seem to depend on the coat though. I've gone back to handstripping with Misty as it was making some of the hair on the back of her neck curl up and look coarse. It never appeared to affect Jimmy's coat though - although he had a nice, natural non trim one that didn't need coat kinging very often. I'd still say it's a handy tool for us pet owners that might find handstripping too much work and time consuming. The elastic band through a spaniel comb does give a nicer finish though, the coat will end up sitting flatter.
