Compact 99-key layout

The Vszerda S99 is a 96% layout keyboard that keeps a numeric keypad while reducing desk footprint. It uses membrane clicky switches for tactile feedback and a creamy feel. The Gradient Purple finish and 16.8 million colour RGB backlight with 16 preset effects suit gamers and home-office users who want a colourful, space-saving input device.

Tri-mode connectivity and knob

Bluetooth 5.0, 2.4 GHz wireless and USB-C wired modes let the board pair with multiple hosts such as a PC, Mac or Xbox. A dual-function rotary knob controls volume, connection switching, backlight brightness, speed and colour modes without software. Macro software adds per-key lighting customisation and key remapping for deeper personalisation.

Battery-powered freedom

The internal battery powers the RGB lighting and wireless links for extended sessions away from a cable. At 17.4 in by 7.28 in by 2.0 in the board fits most desks while the foldable two-stage stand offers two typing angles to reduce wrist strain. Membrane switches keep acoustics quieter than full mechanical clicky boards, so shared spaces stay comfortable.

Questions about this item

Will the clicky membrane switches on this 99-key keyboard need replacement after heavy daily use?

The clicky membrane switches are built into the keyboard and are not user-replaceable; if a key fails the whole unit would need service.

What limits battery life first when the RGB backlight runs at full brightness all day?

The internal battery drains fastest when the 16.8 million-colour RGB lighting is kept at maximum brightness and the 2.4 GHz wireless link is active continuously.

How warm or noisy does the keyboard get after hours of continuous typing and lighting effects?

Membrane switches run cool and the clicky sound level stays constant; no active cooling is present so the chassis remains near room temperature during extended sessions.
