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

Not build sturdy enough for vigorous erasing. The business end cracks.

Great Product. I bought it to go with the Pilot Dr. Grip mini mechanical pencil and I like the light weight and length which allows me to apply more force while erasing drawn lines on my maps or any notes that I need to erase while traveling. It will be in my pack for all future trips.

These erasers look better in real life! The plastic is very hard and matte, not like the usual shiny, easily-cracked plastic barrels you may encounter elsewhere. I used to use pentel clic erasers since they were readily available in most stores, but I wanted something even more accurate for drawing since I tend to draw small. The diameter of these erasers are smaller than the pentel clic erasers that I mentioned, and the eraser itself is smooth and doesn't smudge! The eraser you get is quite long, too, and you can buy refills at a very affordable price. I was going to go with the mono precision erasers, but I'm glad I opted for this one, it's perfect (and it's nice to look at, always a bonus for me)!
