The cases are perfectly sized-- they hold the 11 pills I take every morning with room for a few more (and several of my daily pills are large) but the whole thing is nice and compact, so it fits well on my little nightstand.
I love how the individual days are removable; each container is clearly marked with the day of the week, with morning and evening symbols on its compartments.
All the parts are sturdy and well-made, for a very reasonable price. All around win!
