BlackWidow Stealth
Mechanical Gaming Keyboard

Mac / PC / USB
Tested to Win
For Serious eSport Competition
Go ninja with the Razer® BlackWidow Stealth. An internal mechanical key architecture has been developed by elite Razer mechanical engineers. Tested and validated to meet the demanding needs of the world's best eSports athletes.
10 Key Rollover in Gaming Mode
Unlike traditional keyboards that can only register up to 3 simultaneous key presses, the superior anti-ghosting technology built into the Razer BlackWidow allows up to ten simultaneous key presses to obliterate the competition more effortlessly. Actuate as many keys as you have fingers, and have all of them register accurately and quickly in-game.
Fully Programmable Keys
The keys on the Razer BlackWidow Stealth ensure less time is needed to actuate each key so you can react faster to situations and enemies. Your fingers can move quickly between the keys, ensuring your entire master plan for gaming domination is executed instantly.
Durability for Your Gaming Needs
While conventional mechanical switches are made primarily for typing, the Razer Mechanical Switches have been designed from the ground up specifically for gaming. These switches offer incredible keystroke accuracy, making sure you never miss a critical strike. The Razer Mechanical Switches are also ultra-durable to allow up to 60 million keystrokes, as compared to the 50 million keystrokes of other conventional mechanical switches.
Razer Synapse 2.01
Razer Synapse 2.0 is cutting-edge, intuitive software that functions as the Razer BlackWidow's brain, automatically syncing the gaming keyboard to a cloud server to download driver and firmware updates, while saving your individual settings. Sync your custom settings and macros automatically with this unified configurator, allowing customization of all your Razer products with a single login.
