Alvin, Battery Operated Eraser, Auto Erasers for Drawing, Painting, Sketching, Drafting, Architectural Plans, Comes with 8 replacement erasers - Blue

I bought the eraser because I messed up addressing Christmas cards for my company. I got the eraser really fast, thank you. It did the job I needed it to do. I wish it came with different options for erasers, for ink it needs a harder eraser, but I was able to improvise and made it work.

Great upgrade from the old ones. Light and easy to use. It will erase everything except sadness.

bought for daughter's art class and she loves it! Works well. Had to use it for sketchbook design. Beyond expectations

I use it for drawings for construction. I used a plug in eraser for years that finally gave up the ghost. Tried another cordless one and it was not strong enough. This works pretty well although a stronger motor would help. Overall acceptable.

Too soon to judge durability, but the vinyl eraser fits very loosely in the business end of the eraser

Love this eraser. It is do easy to use and doesn't damage the paper.

Bought this for my husband. He’s an avid drawer and he absolutely loves this eraser. Great for anyone that wants to refine their sketching process.

Mechanically this does what it supposed to do and it came with all its parts unlike another brand battery eraser I purchased and returned. However, what ever the composition of the eraser itself leaves a lot to be desired, that part of it does not seem as well thought out as the holder. The eraser discolors the paper leaving a kind of grey smear on or in the paper fibers largely immune to further erasure. Hand erasing depending on the product does a better job, but is a labor intensive. In that regard the Staedtler Mars Plastic eraser did a better and cleaner job over all (there may be comparable products). Kneaded erasers were adequate and work well in tight spaces but tend to drag and catch on the paper sometimes tearing the fibers and quickly became dirty with what ever was the lead compound without lessening its erasing capability.
