Pros and Trade-offs

Your primary need dictates the choice. If you want an all-in-one tool with a physical screen for calculations and prefer the reliability of a 2.4 GHz dongle, the 8BitDo Retro18 is the clear pick. If you work in low-light conditions, value a lighter, more compact device, and need explicit Mac/PC keycap labels, the Azio IZO is the better option. Both are competent hot-swappable numpads that successfully blend numeric input with calculator functionality.

Which Keyboard Is Better for Your Needs?

The 8BitDo Retro18 wins for gaming due to its included 2.4 GHz dongle and for content creation with its built-in screen.
