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.

This is a pretty good stick eraser except for one thing; don't ever take the tip off. If you do and then put it back you might start a small hairline body crack that will eventually cause the tip to fall off. I fixed mine with crazy glue and its fine now, except for the cracks! For the price its very hard to fault and I would buy yet another (have two already).

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 use this all the time when I am sketching. I have none of the slippage issues and have always found the performance to be perfectly within the range of what I am expecting.

I have used this to erase pencil lines that have been inked over already and almost never have an issue with the eraser streaking the ink (after a bit of drying time). It doesn't pick up too much in the way of residue either, which is very nice as I don't need to "clean" it too much on my jeans.

Highly affordable as well. I've had mine for well over a year and I still haven't needed to use a refill. I might just be stingy, but I can't tell.

Love this eraser! All the convenience and maneuverability of the ubiquitous "Clik-Erase" but with an excellent eraser - soft touch, clean erasure, so perfect!

Love this eraser, used it a lot when I was classically animating

This is an AWESOME eraser, but the spring of mine keeps popping out so I use the Mono Knock 3.8 now.

Slightly misleading, the eraser is actually only 5mm wide, not 10mm. Unless they were talking about the tube itself which just seems odd. If you notice the print at the top of the tube says medium which means there probably is a large version that has a standard 10mm eraser in it. Would be fantastic if Jet Pens carried it!

Soft eraser, easy to erase slim lines, dark lead tends to build up fast on the eraser and smudge so I recommend using a harder=lighter pencil lead 2H-4H if you want to use this eraser regularly. Solid construction, simple mechanism, I like the fact it is see through and that you get a good amount of refills for a fair price.

Years ago Mitsubishi made these for Faber Castell under the name TouchMatic. They only came in black. The eraser was so small that I could get into tight spaces with it to erase fine detail. I liked the TouchMatic so much that I bought a box of a dozen just to get the refills. When I ran out of refills I was dismayed to find that they were no longer available. I looked on line time and time again for them to no avail. Then I came across the E-Knock. I discovered, to my delight, that it was the old TouchMatic reincarnated! I was elated! Now I not only have a new source for the refills I have a choice of a few delightful colors for the bodies as well. Kudos, JetPens, for bringing delight to this old heart.

This has to be the best eraser I have ever used. Great value and excellent product. I highly recommend it.

I am an engineering major, and naturally I'm doing a lot of math all the time. This is great for fixing all those little mistakes. The eraser quality is much better than other similar erasers. Mine gets used a lot as my go to pencil is a kuru toga and we all know the erasers on them aren't worth...

I love this eraser! It lasts a pretty long time and erases very well especially on colored lead

This eraser, I don't like because the eraser retracts when pressure is applied. The Knock 3.8 eraser does NOT do this.

I have been using this eraser for about 2 weeks now and I am really pleased with it. It is comfortable to hold and use, the clip makes it easy to attach to places, it is pleasurable to look at, and erases very well.

My only complaint is that the very top of the barrel has cracked (I am not sure how it happened), it is not affecting the performance at all but I hope it doesn't get worse.

I use this eraser a lot since I use a Kuru Toga and those erasers are so tiny I would have to buy a ton, because I erase quite a bit. Good price and the refills are also at a good price. This is a great eraser.

I've had this eraser for awhile now. The eraser is stiffer than other varieties and erases big blocks of text with ease. I have never torn a page(knock on wood) with this eraser unlike other mass market brands I've used. Overall I think this is a great value and would buy it again.

Erases very well. I've been using this E-Knock for a week already and I love how cleanly it erases. It's a nice eraser to use with my KuruToga which doesn't have the best eraser included on it. My problem with this eraser is that the black piece where the eraser comes out, the tip at the bottom, comes off so easily. I can't tighten it or turn it to prevent the black piece from coming off. This is very annoying and I'm hoping I will not lose the tip one day if it falls off when I'm unaware. If it weren't for this little problem, this eraser would be perfect.

I absolutely adore this thing! This is the best stick eraser I have ever had the pleasure to own! I've had the standard Pen-tel click eraser, staedler peel away eraser and the tri-erase to name a few! This one, by far, surpassed them all! The casing is excellent, with a solid plastic body and wonderful color; also with and excellent grip on the eraser. The eraser itself is soft and very gently on paper yet erases very well! I'm already ordering another eraser piece!

Very good eraser! it is perfect for students. the eraser inside is good quality, though it runs out fast. i personally think that if the plastic was opaque and a little bit heavier, it would look slightly less cheap. However, for 1.50 it is good.

Easy on the paper, durable when used properly. Solid body and good diameter of the eraser.
