Pros and Trade-offs

Your primary need dictates the choice. If you require a numeric keypad, arrow keys, wireless freedom, and a control knob for data entry or creative work, the Epomaker TH33 is the clear and more functional option.

Consider the TH33 the generalist tool and the KB0304 the specialist accessory.
