Compare Redragon Eclipse K720 Pro vs PENUMBRA K687 Differences Side by Side

This comparison is for buyers deciding between two premium-feeling, 75% layout Redragon keyboards with CNC aluminum cases and gasket mounts. The choice hinges on whether you value the K720 Pro's tri-mode wireless connectivity and smart TFT screen enough to justify its higher cost over the strictly wired, more affordable K687.

Pros and Trade-offs

Your budget and need for wireless connectivity should guide this choice. If you want the freedom to connect wirelessly to multiple devices and value the novelty of a customizable TFT screen, the Redragon Eclipse K720 Pro is worth the extra investment. If you primarily use a single desktop PC and prefer a simpler, more affordable setup with the same premium aluminum build and typing feel, the wired Redragon Penumbra K687 is the sensible pick.
