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

This comparison is for buyers deciding between two very similar high-value 75% aluminum keyboards from Redragon. The choice is difficult because they share a core feature set: tri-mode connectivity, gasket mount, hot-swappable sockets, five-layer noise dampening, and a CNC aluminum case. The decision ultimately hinges on whether you value the Eclipse's integrated TFT info screen or the Penumbra's stock PBT keycaps and slightly lower cost.
