How we scored them
The Office Score weighs ergonomic design, build quality, value, safety and warranty. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| X9 Split Ergonomic Keyboard | 9.8 | 35 | 22 | 21 | n/a | 3 |
| Nulea 3D Curved Split Keyboard | 9.8 | 34 | 21 | 21 | n/a | 3 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
