Razer DeathAdder V4 Pro mouse review: Serious bite

Finding a good gaming mouse that balances performance and comfort can be a challenge. Fortunately, the folks at Razer have delivered just that with the Razer DeathAdder V4 Pro. Unlike many Razer products known for their flashy aesthetics, the DeathAdder V4 Pro opts for a more understated design, focusing primarily on comfort and top-tier performance.

### Design and Build

The Razer DeathAdder V4 Pro is impressively lightweight, weighing just 56 grams (1.97 oz.). Inside the box, you’ll find the mouse equipped with Razer’s Optical Mouse Switch Gen-4, along with a True 8000Hz Wired/Wireless Polling dongle and a USB-C-to-A cable. Setup is straightforward with plug-and-play functionality, though advanced customization can be managed through Razer’s proprietary Synapse software.

Visually, the mouse sports a simple black design that forgoes Razer’s typical RGB lighting. While this might seem plain at first glance, Razer’s intent is clear: to prioritize function over flashy looks. The ergonomic shape feels great in hand, especially for those who favor a fingertip grip, making it ideal for extended gaming sessions.

### Performance and Features

One of the standout features of the DeathAdder V4 Pro is its adjustable sensitivity. Switching between 400, 800, 1600, 3200, and 6400 DPI (dots per inch) is possible with a single button press. However, the button’s placement along the bottom of the mouse — where it also functions as the power button — isn’t the most convenient.

Managing the mouse’s impressive polling rate is best done through Razer Synapse. While opinions on Synapse may vary, it proves very effective here. The software allows you to adjust the polling rate from a low 125Hz up to an astounding 8000Hz. Additionally, there’s a smart polling rate switcher that automatically changes the rate when games run in full-screen mode, dropping back down to 1000Hz when no game is detected.

The included dongle features a three-LED display that quickly communicates connection quality, battery level, and polling rate at a glance.

### Real-World Use

The DeathAdder V4 Pro performs exceptionally well across various game types. For casual or less demanding games like Hearthstone, Keeper, or Hades 2, the default 1000Hz polling rate is more than sufficient. When it’s time for competitive shooters such as Battlefield 6, Marvel Rivals, or classic Team Fortress 2, increasing the polling rate enhances responsiveness.

The mouse also includes two extra side buttons, which can be programmed with custom functions. Users can create multiple profiles tailored to different games using the Synapse software.

Battery life is another strong suit. Even at the maximum 8000Hz polling rate, the mouse lasts several days on a single charge. If you’re using it more casually, the battery can stretch to several weeks before needing a recharge. Plus, the DeathAdder V4 Pro can maintain its 8000Hz polling rate even while charging and operating in wired mode—a feature that gives it a notable edge over many competitors.

### Final Thoughts

Beyond raw performance, comfort is where the Razer DeathAdder V4 Pro truly shines. The clicks have a hollow yet satisfying sound, and the optical scroll wheel is highly responsive (though its long-term durability remains to be seen). The battery life is impressive, and the dongle’s dome-shaped design is both practical and user-friendly.

Priced at $169.99, the DeathAdder V4 Pro is on the higher end of the market. However, for gamers who can justify the cost, this mouse offers a superior blend of comfort, performance, and versatility. Whether you’re aiming for a higher kill count or simply want a reliable, ergonomic gaming mouse, the DeathAdder V4 Pro is definitely a winner.

49ers Insider declares 100% need to make trade after disaster vs. Texans

San Francisco 49ers fans and front-office observers woke up Monday asking the same blunt question: Do the 49ers need to make a trade?

After Sunday’s 26-15 loss in Houston, the short answer feels obvious, according to David Lombardi of the San Francisco Standard.

C. J. Stroud ripped the 49ers for 318 yards and two touchdowns, completing 30 of 39 passes, per the ESPN box score, as the Houston Texans turned what should have been a manageable matchup into a passing clinic. The Texans achieved this without key receivers Nico Collins and Christian Kirk, which makes the performance even more glaring for San Francisco.

San Francisco managed a late push, with Mac Jones throwing for 193 yards and two touchdowns, but the 49ers’ defense couldn’t generate any pressure on the quarterback. Houston finished with 475 yards of total offense, and the pass rush barely registered—an alarming sign for a team still built around forcing pressure up front.

That lack of consistent pressure allowed Stroud to pick apart both zone and man coverages alike.

This is where the trade conversation stops being theoretical.

The 49ers currently rank near the bottom in sack and pressure metrics, and Sunday’s game exposed how fragile the defensive unit looks when injuries stack up. The team lost key defensive contributors during the matchup and saw youngsters thrust into heavy reps.

Edge rushers are typically the more plug-and-play pieces available in midseason deals, and history shows San Francisco has been able to plug gaps effectively when it finds the right target.

General Manager John Lynch must decide whether to buy now or trust internal development.

The locker room has shown fight—this team was competitive deep into the fourth quarter—but momentum and confidence can evaporate fast.

Trading for a disruptive pass rusher would cost draft picks or players and might mean overpaying. Still, if the goal is to protect the playoff window, paying a premium for proven pressure could be necessary.
