Pulsar X2F CrazyLight: Strengths & Caveats
✔ Advantages
- Ultra-lightweight 29-gram structural design built from an ABS and nylon composite blend
- Pulsar X2-S optical sensor delivering up to 42,000 DPI, 800 IPS tracking, and 70G acceleration
- Native 8,000 Hz wireless polling supported by the 8K Link Dongle with onboard hardware controls
- Pulsar optical switches rated for 100 million clicks paired with a dust-resistant TTC Gold encoder
✖ Documented Caveats
- Truncated 87.5 mm chassis strictly accommodates fingertip grips with zero palm support
- Sensor 20K frame rate lock and sustained 8K polling noticeably increase power draw and shorten battery life
Glorious GMMK Eternal: Strengths & Caveats
✔ Advantages
- Triple-layer sound dampening for a solid, refined sound profile.
- 96% layout provides a numpad and function row in a compact footprint similar to a tenkeyless board.
- Hot-swappable switches allow for easy customization of switch types.
✖ Documented Caveats
- Keycaps are ABS instead of PBT, which may wear faster or lack the desired texture for enthusiasts.
- No wireless connectivity option available.
- Software support is limited to Windows only.
