Effective!
My kitten is still a little small for this brush, but loves it just the same! As you can see, she still thinks it's a play toy, so it's hard to capture a good image. She also doesn't shed much, so there wasn't enough fur to "eject" out of brush. I can say, though, that the mechanism that releases the hair works very nicely. The only negative about the brush is that, even though the needles are capped at the end, they're still a bit sharp.
