Also the Aergrind fits inside the Aeropress and it is by far a better grinder with quality burrs. It's only a wee bit pricier, so it is my choice (with the Aeropress).
Of course there are better hand grinders, but Aergrinder's price, portability and size make it a clear winner for the Aeropress).
James Hoffmann recently did a good Youtube review on hand grinders.
