Query: The best

I have purchased many mechanical pencils in an effort to find one that really works for me and this has turned out to be the best. Because it senses the needs for lead, I never end up with too much lead out and breaking off and I'm never fumbling for lead. If I have a meeting coming up I just pop out the cartridge and the black cartridge cap an refill before I go.These are a great item.
