I really like these! I don't have a lot to compare them to, but as a product I've yet to find anything wrong with them. They sharpen well, give off nice color that varies with pressure, and don't break easily. With a manual sharpener, I can get them to a nice, writeable tip, almost like a regular pencil. One thing I don't like is the packaging, as with most boxes like this. It was so hard to alway put the pencils back in without everything going in the wrong place, so I keep them in a cup on the table, and some in a pencil case for travel.
