I'm not really impressed

The grip is not comfortable, and the mechanism that rotates the lead rotates in such small increments that I don't think it's effective. It's also not that much thinner than 0.5mm pencils that are much more common. I'd avoid this and spend a little more on a better 0.3mm mechanical pencil if you really want one. I only bought it to try because I found 9 tubes of replacement 0.3mm pencil lead in a vacant desk at work.
