I bought one of those on a whim a while back, and I was pleasantly surprised with how good it was. Quality control is always kind of a crapshoot with those cheap Chinese pen brands so I don’t usually get my hopes up, but even though the pocket clip on mine feels loose and pretty janky, the actual pen itself is really solid, and has a surprisingly good nib for its price point. I ended up carrying it with me a lot because it’s not only a nice compact size for a pocket pen, but it’s cheap enough that I won’t be devastated if I lose it.
