Review (4/5): Simple, cheap, works for us!
I have a golden/border collie with ear tufts and longer hair on his legs that get stuff stuck in them -- especially all the fancy bark dust I bought in the spring. I use this as an outside brush to get a quick brush out so he doesn't track little bits inside. On his shorter hair areas I have to be careful to not apply too much pressure because that can irritate his skin. On longer hair it gets through tangles pretty well before they start. He also hates being brushed so every little bit helps. Love how cheap it is. Got pink because they were out of grey, but my dog hasn't complained. ;)
