– Precision Battery Operated Eraser, Kit with 8 More Replacement Erasers, 2301931

This electric eraser is excellent, comfortable to hold and using the power button has not caused me any issues, for highlighting it's exceptional especially with the design, the spindle speed is sufficient for the job in hand, for larger areas of erasing I'd use the traditional method! The small eraser hasn't transferred pencil graphite anywhere else so I've had no problems with smudging. Summary....it's easy to use, the battery is easy to install and it will last many years! Highly recommended.

Really great for erasing in small, hard to get to areas, I'm very pleased with it

Following a review (by that on-line drawing tutor bloke with five pencils) in which he rubbished this brand, I was rather skeptical about its performance. He absolutely raved about the Sakura in his comparison playoff, so after much deliberation I bought the Sakura - but including mail from USA and a couple of refill packs, it cost me about sixty-five quid. Ouch. It _is_ brilliant though. Sakura SE2000 Electric Eraser Kit, Black For the sake of hardly anything extra I also bought the Derwent and a couple of boxes of refills. Good for chucking in a bag for out and about, I thought. The Sak comes with Duracells, my Derwent came empty. The Sakura IS better. It is more solid and has more torque and a bit less vibration. Is it more than ten times better, commensurate with the price difference, though? No. It's maybe half as good again - twice if I'm being generous. With fresh batteries, they both work very well and clean up pencil lines more accurately than could ever be done by hand, but there's no real difference in their performance. The Sakura is maybe half a hairs width more accurate - maybe. I suspect it's just a tad more comfortable. They both eat batteries. I get through batteries faster than the tiny eraser refills and neither machine likes being pressed hard onto a drawing but that is neither necessary nor desirable. With tired batteries the Derwent will still have a go where the Sakura ... well, it doesn't stall, it just seems less keen. It's marginal, though. You'll need loads of cheap batteries or a set of rechargables to get the most out of these. AAA unfortunately. Duracells are ideal, apart from the price. Rechargables are slightly lower voltage, remember, so don't perform _quite_ as well but I've happily used 15 for a pound Quidland el-cheapos with no _real_ problems. They still work when the batteries tired, but they aren't as lively, therefore less precise and crisp and tend to bog down a bit if you press on even slightly and it can be a little frustrating in comparison. Buying the Derwent would have been perfectly adequate, realistically. I don't regret buying the Sakura, but if I hadn't got it - say I'd tried both out at a mate's house with a view to buying one, then i'd happily buy the Derwent. If I were in the States where the prices would be more similar to each other than they are in the U.K. then I'd get the Sakura. Both use the same sort of folded steel "alligator mouth" collett which squeezes on the rubber when the fold is pushed into the motor spindle. It works fine down to about 4mm of rubber and they are both simple to adjust. I've never had a rubber fly out or get irretrievably stuck. I don't see how anyone using either correctly would do. I bought a second Derwent to keep with my coloured pencils. No problems there, either The review that coloured my buying judgment was done by an obsessive-compulsive xxxxhead - if you see his tutorials (Buy my exciting five hour video on how to colour-in a nose!!!!) you'll understand. I had to go on the witness protection scheme and have plastic surgery to stop receiving the hard-sell emails but there is no other product comparison information available. I am also not SELLING either of the products, and maybe there's a hint in there too. The Derwent eraser is fine, it really is. if my kit got stolen tomorrow, I'd re-equip with the Derwent. BTW a few people were amused and uncomprehending at the whole notion of an electric eraser; incredulous, even. It was regarded - by non-artists - as something like buying an electric tea-stirring spoon. It hadn't occurred to any of them that this wasn't "lazy erasing" - it was _precise_, no-smudge erasing If you need an electric and you know what it's for, I'm sure I can recommend the Derwent and you'll ve happy with it.

My wife and I do puzzles, crosswords and similar, using pencil so we can erase mistakes. These are wonderful, robust, precise and perfect. Highly recommended.

Works perfectly, long battery life and extra sticks to work with

I've never used one before but was convinced watching a lot of people using them - the crucial aspect being, erasing with the precision of a pencil. In essence, one can draw with the eraser which is great for highlights and building textures however, I mostly want to erase fast, clean and with precision - it does deliver very well. Why getting a battery eraser over a kneaded one? Precision and speed. The erasers can be used by the edge or sharpened on sanding paper (or nails sander) to a very fine point. For airbrushing it's crucial - the layers of acrylic are hard to peel with a normal eraser (a knife works but at risk of damaging the paper/canvas surface). On regular pencil and paper drawing, it's fast and precise - lets you draw more loosely knowing you can erase very selectively therefore, redrawing less, sketching faster and getting less frustrated. Put your own batteries in and it works right away - light pressure and moving against the friction yields the best results. I hold it much like a pencil with the index finger over the power button, it's comfortable and well balanced. I did notice a rattle on mine - it really shouldn't make more noise than a toy motor spinning - so I checked if the eraser holder was hitting the casing while spinning (it was not, plenty of clearance). I knew it was internal vibration so I opened it up praying gently with a plastic along the seams. There's really nothing to these devices - the clear casing ones show us that - it's just a toy motor with a plastic shaft adaptor in which the eraser holder fits snug. There's no precision engineering here so unbalancing causes vibration and gaps between the motor and the casing cause the rattle. A tiny amount of blu-tac packing between the motor and the casing, closed it back neatly and it now works like a charm. The manufacturer could have thought of that and packed the casing with foam tape - I doubt anyone will bother opening it as I did: I'm an engineer, it's an occupational hazard :) Derwent makes good products and this battery eraser is no different.

Purchased for some map work where using a 2B pencil I am required to plot coordinates onto a chart to determine locations of objects. To be absolutely honest, I found that it was little better than using a simple rubber/eraser and the only benefit I could identify ws that the eraser heas is small. Inserting 2 AAA batteries into the handle, which weere not supplied adds to the costs and detracts fron it being a value for money item. In terms of operation, it is easy to use, but offers liitle to the purpose of erasing pencil marks. It is simple to grip, is effective but as to whether it is of purchasing is open to interpretation.

Honestly wouldn’t ever know that this was the missing tool from my sketches, battery lasts a long time and the ease of use is great even for beginners, my sketches won’t ever be the same again. Extra bonus for the fact it comes with extra eraser heads to replace when it’s worn down

The Derwent Battery operated eraser is rather good. Good to create highlights/light tones while sketching. Also, find it easy to erase any errors.

Ich bin mit dem elektrischen Radierer von Derwent sehr zufrieden. Er ist ein hilfreiches Werkzeug für alle, die gerne zeichnen und Wert auf exakte Details legen. Meine Erfahrungen: Präzision: Der Radierer ermöglicht ein sehr punktgenaues Arbeiten, was mit einem herkömmlichen Radiergummi kaum möglich wäre. Besonders zum Setzen von Highlights oder zum Aufhellen kleiner Bereiche ist er ideal. Handhabung: Er liegt gut in der Hand und lässt sich leicht führen. Auch der Austausch der Radiergummis ist unkompliziert. Zubehör: Dass bereits 8 Ersatzradierer im Lieferumfang enthalten sind, ist ein schöner Pluspunkt für den Start. Fazit: Ein tolles Tool für Hobby-Künstler und Profis gleichermaßen. Das Preis-Leistungs-Verhältnis stimmt hier absolut.

Very useful item. Sent very quickly and packaged well. Very pleased.

これと、100均でも購入してみました。 全然違います。回転数が劣るのだと思います。 細かく消すのが100均のは難しいですが、これは小さな・で消せます。 ただ。しかっり握らないとブレるので、制御するのが大変なのと、スイッチを押し続けるのが大変。これは100均のも同じなので、仕方ないのかも。

The eraser is very easy to operate. And is very efficient, speedy erasing. However, the casing is rather smooth, so take some time to grip it properly to switch on the power. On the whole am happy with the buy.
