Years ago Mitsubishi...
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.

For erasing small items, I used a Tuff Stuff for years until they were discontinued. This is the best replacement I've found and actually outperforms any other stick eraser by a long shot. Very smooth and erases marks completely. You won't regret buying this--make sure to get some refills.

Eraser is ok but not great. The plastic body cracked where it has a screw-in tip, got to reorder until better one is produced.

Verified Purchase
I love this little handy thing, but i was surprised at how slim the eraser was. I don't mind the thin eraser, it erases perfectly in between the lines. I bought 2 just in case 1 broke, and a pack of the dust-gathering eraser refills (they fit in this model perfectly). I highly recommend this, but be sure you know if a 5mm diameter eraser is either a pro or con for you.

I really liked the eraser at first, but after just a couple of exams the clear plastic, near the tip where the black piece screws in, cracked in 2 places. It is now very difficult to erase. I'm very disappointed to write this review, but I hope other people take caution before purchasing this product.

the Uni E-Knock removes .5mm 3B lines well. I am pleasantly surprised at how precisely I am able to erase around my small writing.
Though I enjoy using this eraser very much, I have had the same issue as another owner with the barrel cracking at the threads where the black tip screws on. When the tip comes loose the eraser wiggles around in the barrel and becomes difficult to use. The clip also broke on mine, but that did not affect the function in my case.
As a hack fix, I wrapped several turns of a thin wire around the outside of the threads and taped the wire in place so the cracks cannot expand and allow the tip to come loose. This has been working well for a few months, but I am disappointed that the plastic fractures so easily.

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

Verified Purchase
Works well, the refills are cheap, and it is not at thick as other "mechanical" erasers. So it doesn't use as much space in my already full pencil case.

Verified Purchase
Others wrote that the quality of this eraser was very good, so i may have just received a lemon. The one I received is terrible, very low quality compared to standard erasers. It does not erase well at all, and is very hard. I will not be buying any more of these.
