I really liked this item and I would rate it 4/5. The rotating eraser really helps erase things easier, and it rolls on easily onto the page. The mechanical pencil is really long too, and I've hid this item for over 3 weeks and the pencil is still working and I haven't had to refill the lead. One problem I'd have to say I had is the lead in the pencil broke many times, but other than that I'd recommend this item to other people, especially school students, because as a student it has been very helpful to me.
