Query: not as good as I expected

Hello, everyone! When I was looking for the eraser, I didn't need anything special, so I decided to get the cheapest. Well, I was rather upset, when I tried to erase something written with regular HB pencil. It was smudging... badly. It has 2 types of eraser: white and gray. Both of them smudge. Maybe, if you change the eraser (use the one that you rely on), it'll do the work in a proper way.Second characteristic is that it's less comfortable than the one by Staedtler. The good thing about it is that it's compact and light... and cheap.I really believe that, if you change the eraser itself to the better one, it can perform much better (the way you want, maybe), because the motors in these electric erasers are almost identical.Best wishes!
