Outdated Product
Full-size wired solution from 2025, combining a classic ANSI layout with advanced fast input technologies and enhanced ergonomics. Structurally, the model is a "skeleton" where switches are mounted directly onto the top plate, which not only simplifies device maintenance but also makes the operation of 10 preset RGB lighting modes visually more striking. The central component of the device is the proprietary BLMS Red Plus mechanical switches with linear travel, specifically calibrated by engineers for force and actuation point to enhance gaming speed. The A4Tech Bloody S525N Red Plus Switch gaming keyboard offers complete customization freedom through Hot Swap system support: the PCB is compatible with both 3-pin and 5-pin switches, allowing them to be changed without...soldering or disassembling the case. To reduce wrist strain during long sessions, a detachable wrist rest filled with soft memory foam is included. The electronics provide a polling rate of 1000 Hz (1 ms response time) and include a 4 MB memory module that stores up to 120,000 macros, customizable via KeyDominator software. The durability of symbols is ensured by the use of double-shot technology for both layouts, and the likelihood of accidental keypresses (misclicks) is reduced due to the special slanted shape of the keycaps.

How to choose a gaming keyboardLet's look at the differences between the types of switches and additional equipment for gaming keyboards

"Hot" Adaptation Technologies

The A4Tech Bloody S525N Red Plus Switch keyboard combines current gaming capabilities with an affordable price. This is a full-size model for gaming that can be flexibly customized to personal preferences or specific tasks. The main advantage is the proprietary linear mechanical switches BLMS Red Plus with Hot Swap support. Thanks to this, the user can change the character of the press, key travel, sound feedback, tactile response, and actuation force with compatible switches, which are purchased separately.

The standard switch resource reaches 50 million presses. Software customization is done through the Bloody KeyDominator application: the user can create templates, record macros, and save them in the keyboard's internal memory. Therefore, the set parameters remain available even when connected to another PC or laptop. The model is well-suited for dynamic games, RPGs, simulators, and MOBA, while the 1000 Hz polling rate and 1 ms response time help to respond promptly to each action.

Durability and Comfort

The keyboard is designed in a Skeleton construction, making the RGB backlighting more expressive, and maintenance easier. The user can easily clean the body, change keycaps, and install other switches. The caps are made using the double-shot method, so the symbols do not wear off over time.

The ergonomic shape of the keys with indentation reduces the risk of finger slipping during active gaming and enhances control accuracy. An additional plus is the detachable magnetic wrist rest with a soft filling, which makes long gaming sessions more comfortable.
