Review (4/5): Better than similar brushes
I've used this the last 3-4 years. It's pretty good, the small brush covers the gray exactly where you want it, but it may pull some hairs, just like the rest of similar products. There is a tiny comb on the other end but I don't use it. I've noticed that it doesn't run, even wet/drenched, and it shampoos out very easily. However, keep in mind that a bottle will only last 4-5 weeks if used every day and sparingly.
