I have it since my second year of school and it's still alive. It shows its little problems after three years, but it's okay, it doesn't matter. When I bought it, the nose adjustment was automatic, but now I adjust it a little more manually (it has the lazy characteristics of a mechanical one). I love the back part for the eraser. And also, for the many years I have had it, it has sentimental value now. Almost all of my cats have bitten it (some of them are no longer alive). Immortal, lightweight, cheap.
If you're too lazy to write with the same pencil your whole life, just don't buy it.
