The 2016 version of the BlackWidow Ultimate Stealth Mechanical Gaming Keyboard from Razer features Razer gaming optimized orange switches, which have a 45g actuation force with a tactile feel and no audible click. These switches are rated to last up to 60 million keystrokes and allows for fast actuation without having the need to bottom down into the keystroke each time.
The BlackWidow Ultimate supports macro functions and on-the-fly recording using Razer Synapse software. This model has green LED backlighting, and the Synapse software allows you to customize lighting effects, such as starlight, ripple, and wave.
On the side of this keyboard are a USB pass-through port and a combo microphone & audio jack. It connects to your computer via a braided-fiber USB cable and in order to access all of its features and options, you will need to download the Razer Synapse software.
