I have about a week using precious drop on Leroy and I like it so far, it leaves his hair soft and shiny and he doesn't seem to get any knots.
I do dilute it with 1 part water and 1 part precious drop even though it is ready to use, since I read that it can make their coat a little stiff in this thread
