Query: Fine for press/drip coffee, not espresso

I bought this coffee grinder because I had heard that burr grinders were good for grinding beans for espresso. Maybe other burr grinders are, but this one is not. It produces perfectly acceptable grinding for use in a french press or a drip coffee maker, but even on the finest grind setting, it comes nowhere near a fine enough grind to make espresso. Also, I have noticed that the grinds are not very uniform in size; on the finest setting there is some finely ground coffee but there are also a lot of larger grounds. I don't notice any obvious improvement in coffee flavor over my whirly-blade grinder. The search for a good coffee grinder goes on.
