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!

The eraser is good but sometimes it smudges pencil marks and that is harder to erase. Other than that, I would recommend it. The body is sturdy and doesn't break unless stepped on (or something similar).

Does exactly what you would imagine. I use ain stein 2B lead and find myself reaching for this quite often. I have the Kokuyo Student eraser that I tend to use as my desk, but while in class etc, I always reach for this E-Knock. I'm a math student (and tend to write fairly small in general) so this allows me just erase with some precision in comparison to a standard block eraser
