This article covers Razer DeathAdder Essential ゲーミングマウス 有線 5ボタン 6400 DPI オプティカルセンサー エルゴノミック形状 新ファームウェア適用版【日本正規代理店保証品】 RZ01-02540100-R3M1-N.

Overview

The Razer DeathAdder Essential is the entry-level model of the legendary DeathAdder series, which has sold over 9 million units worldwide. This wired gaming mouse features an optical sensor with up to 6,400 DPI resolution, and retains the classic ergonomic shape that made the series famous. The design is optimized for palm grip, providing comfort during long gaming sessions. Equipped with Razer mechanical switches rated for 10 million clicks, the DeathAdder Essential offers reliable durability. All five Hyperesponse buttons are programmable via Razer Synapse software. Priced around $30-40, it delivers excellent value for budget-conscious gamers.

Connectivity & Compatibility

The mouse connects via a standard USB-A interface, offering plug-and-play functionality on Windows 7 and later, macOS, and Linux. The cable is approximately 2.1 meters long, providing ample reach for desktop setups. For full customization—including button mapping, DPI adjustment, and polling rate configuration—Razer Synapse software is required. Note that Synapse is Windows-only; macOS and Linux users will have access to basic functions only.

Product Info

Released in 2021, the DeathAdder Essential remains a popular choice in the entry-level gaming mouse segment. It comes with a 2-year manufacturer warranty. The package includes only the mouse itself; no additional accessories are included. It is widely available through major retailers like , with a street price of approximately ¥3,980 in Japan or $30-40 in global markets.

Best Use Cases

First, this mouse is ideal for beginner gamers entering competitive titles like FPS or MOBA games. The 6,400 DPI optical sensor provides sufficient precision, and the ergonomic shape supports extended practice sessions without fatigue. Second, it suits budget-conscious users who need a reliable, durable mouse. The 10-million-click switch rating ensures longevity, making it a cost-effective choice for daily use. Third, it works well for users with larger hands who prefer palm grip. The generously sized body fills the hand comfortably, reducing strain during long gaming marathons. ## Alternatives
A direct competitor in the same price bracket is the Logitech G203 LIGHTSYNC. It offers 8,000 DPI and RGB lighting, but its ambidextrous shape lacks the ergonomic contouring of the DeathAdder Essential. If comfort and hand fit are priorities, the Razer model is the better choice. Another alternative is the Corsair KATAR PRO XT, which is lighter (73g) and features a 10,000 DPI sensor. However, its smaller size may feel cramped for users with larger hands. The DeathAdder Essential's larger ergonomic shape provides a more stable and comfortable grip for a wider range of hand sizes.

Things to Consider

This is a wired-only mouse. If you prefer a clutter-free desk or dislike cable drag, consider a wireless model like the Razer DeathAdder V2 X HyperSpeed. There is no RGB lighting. If aesthetics with glowing effects matter to you, look at the Logitech G203 or step up to a higher-tier DeathAdder model. The optical sensor maxes out at 6,400 DPI. For high-resolution displays (4K or above), this may feel insufficient. In that case, models like the DeathAdder V2 (20,000 DPI) would be more suitable. Finally, the mouse is designed exclusively for right-handed users. Left-handed gamers should look for ambidextrous options.
