Model check
RZ03-05850 is the Low-profile Tenkeyless 8KHz. Do not confuse it with RZ03-0552 or HE Magnetic RZ03-0592x.

Travel range
Razer lists 0.1-2.8 mm here versus 0.1-4.0 mm on the standard Pro TKL, so its maximum travel is shorter.

Claim boundary
Razer claims 8,000 Hz and 0.39 ms to USB. A browser cannot verify raw polling or end-to-end latency.

Buyer fit
Shortlist it for low deck height and short travel. Keep your board if you prefer deeper travel or need wireless.

Read the result
Missed, doubled or stuck keys that repeat matter. One clean run cannot prove actuation depth or 8K.

Next action
Test every normal key once. Use repeatable return-window results, not the page as an 8K certificate.
