Although the body is great and has an eraser small enough for those small mistakes, the eraser does not erase very well and i'm sad to say that my normal block erases better than it. Nevertheless, the eraser is still a great buy for its price.

I liked how small and precise the diameter of the eraser was, but I believe this eraser didn't live up to my expectations. It's light and very portable and the color of the pen holder is great. But the eraser part itself did not erase as well as I thought it should. I own a uniball kurutoga, and the eraser my pencil came with erases much better than this. When you write with normal pressure, this eraser leaves enough lead residue that you can still faintly read what used to be written down. This is disappointing, but I believe this is a good backup eraser.

I owned a different knock eraser before this, but I lost it and ran out of refills, so I bought this one to replace it. The eraser is finer than my old one, and is better for erasing pencil out from under pen- especially if it's a type of ink that's prone to fading if it's erased. It works better than I could have hoped, and it's attractive to look at and hold. Good for cleaning up inked pieces!

Haven't used it much since I've gotten it. But it's easy on the eyes and is there ready for me to use. :)
