Product Description

The ACGAM S99 is a wireless mechanical keyboard with a 98% layout, suited for users who want versatile connectivity and a comfortable typing experience. It targets gamers and typists who need low-latency wireless options alongside wired use. Its hot-swappable switches and sound-absorbing design also appeal to hobbyists seeking customization and quieter typing.

Key Features

Offers three connection modes: Bluetooth 5.0, 2.4GHz wireless, and wired USB Type-C, allowing flexible use across devices and scenarios.
SmartSpeed X technology provides a 1000Hz polling rate for responsive input, beneficial for gaming and fast typing.
Hot-swappable sockets support two custom linear switches, enabling switch replacement without soldering.
Large 6000mAh battery supports up to 35 hours of use with backlighting and up to 35 days without, reducing charging frequency.

Build Quality and Typing Experience

Single-key slotted PCB with plate-spring gasket mounting offers moderate typing cushioning and stability.
Four-layer sound-absorbing design and leaf-spring gasket structure reduce noise and improve acoustics for quieter typing.
Keycaps are double-shot PBT with Cherry profile, providing durability and a familiar key shape for comfortable typing.
Switch options include Aurora Ice Cream and Anya linear switches, both designed for smooth, light actuation.

Connectivity

Bluetooth 5.0 suits mobile or multi-device use but may have higher latency than 2.4GHz wireless.
2.4GHz wireless mode offers lower latency, preferable for gaming without cables.
Wired USB Type-C connection ensures zero latency and charging simultaneously.

Compatibility

Compatible with Windows, MacOS, and Linux, covering most desktop environments.
99-key 98% layout balances compactness with function keys and arrow cluster, fitting varied workflows.

Trade-offs

At 1.2kg, the keyboard is moderately heavy, which may reduce portability.
Switch options are limited to two linear types, which may not suit users preferring tactile or clicky feedback.
Firmware and keymapping customization details are unknown, possibly limiting advanced remapping.
