The Razer Boomslang 2000 is a high-end gaming mouse from Kärna, designed specifically for first-person shooters. Priced at $99.99, it aims to justify its cost with a unique ergonomic shape, high precision, and driver features like on-the-fly sensitivity adjustment. The mouse uses a ball sensor and connects via USB or PS/2, with USB recommended for its 125Hz polling rate. Its large, elongated body forces a specific grip style, with the trackball positioned farther back. The build is sturdy, with a metal tin packaging, teflon feet, and a seven-foot cable. Drivers support macro programming, left/right handed configurations, and extensive customization, but have known conflicts with certain USB audio devices like the Microsoft DS80 speakers. Released in 2000, the Boomslang 2000 targets serious competitive gamers willing to endure a steep learning curve for superior control.
