The eraser erases very well, but the mechanism that holds the eraser slips occasionally, allowing the eraser to slide back into the holder. I need to extend the eraser often to compensate. The mechanism only slips when I hold the eraser perpendicular to the paper and am pushing down hard. If you only hold the eraser at an angle to the page, friction holds it in place well and you won't have any slippage problems.

If you are considering this product, the Tombow Mono Knock 3.8 is also worth a look.

I really love this eraser. I've had many different kinds of erasers, and this works the best when writing essays(timed) and drawing. It erases mechanical lead better than a wooden pencil. The only problem I had was the eraser ran out fast for me! Good thing they sell the refills!

I really like this eraser. For me, it is the perfect combination of precision and erasing power - large enough to not feel like I'm burning through the eraser quickly, and small enough to only erase what I want (I use this for erasing written text on 5 mm+ spaced lined paper). The eraser is firm enough not to be pushed back into the body when applying downward pressure, and at the same time soft enough that I've never had any problems with paper movement / dragging / tearing while erasing.

It's attractive, but it's just okay. The eraser (the actual eraser, not the body) has broken on me while rubbing against paper more than once, but I was mainly using it to erase on uncoated book paper. It works fine on bond paper and anything similar to it. I wouldn't recommend refills if you're annotating textbooks.
