Score: 80/100
Redragon K617 Fizz
Score: 85/100Rankings

The Redragon K617 Fizz delivers a compelling budget package with hot-swap linear switches, full RGB, and high-speed polling in a compact 60% form factor, though it lacks dedicated media controls and macOS software.

The Tartarus Pro is a left-hand ergonomic keypad featuring 32 programmable analog optical switches, rapid trigger technology, and per-key RGB lighting. It excels in customization and low-latency input but demands Razer software and has a steep learning curve.
