Derwent USB Rechargeable Eraser, Ideal For Precision Erasing, Professional Quality, 2305810,5mm x 2.4mm

Ottima gomma elettrica con buona durata della batteria e con una buona scorta di gommine di due formati. Consigliato

Outil très pratique

Muito bom q princípio apaga, muito bem espero que dure bastante, perfeito para efeitos no desenho realista, e o fato de não precisar segurar o botão para a funcionar e absurdamente prático

No more batteries needed! comes with 2 different eraser sizes , can be charged via USB , love it really simple to use and you now can just turn it on no more holding the power button on to use! fantastic quality.

I am using this to erase pencil markings in orchestra parts. This eraser seems to remove markings cleanly and is very easy to hold. I appreciate that once pressed, the on button stays on. The angle for the handhold allows me to use the eraser in a way to stay flat and remove the most markings. So far, the eraser appears to be held firmly in place. Recharging takes a bit of time after extended use, but usually within an hour it is back to a green light. Very pleased, met my needs quite well. I also tried the battery-powered Derwent eraser, which needed new batteries about every 2 hours of use, and was less comfortable due to the need to hold the on button with a fair amount of pressure, but it also has enough power to erase well.
