What is a disadvantage of using a space-filling model to show a chemical compound?

A space-filling model shows atoms as spheres that fill the molecule’s volume, so it gives a sense of the molecule’s overall shape and the relative sizes of its atoms. However, the spheres obscure how atoms are connected and do not clearly show the number or type of bonds. Therefore, the disadvantage is that space-filling models do not identify the number and type of bonds.
