Redragon ワイヤレスマウス Bluetooth 2.4G 電池式静音小型軽量左右対称両利き対応最大4000DPI 5段階調整 4ボタン省電力レシーバー収納可能携帯に便利 PC ノートPC Mac対応 (ダークグレー)

Overview

The Redragon wireless mouse, listed on Amazon Japan as 'Redragon ワイヤレスマウス Bluetooth 2.4G 電池式静音小型軽量左右対称両利き対応最大4000DPI 5段階調整 4ボタン省電力レシーバー収納可能携帯に便利 PC ノートPC Mac対応 (ダークグレー)', is a compact, silent mouse that connects over Bluetooth or a 2.4G wireless receiver.

It runs on a single AA battery. It weighs 58g and measures 9.91 x 5.99 x 3.78 cm, so it is clearly built to travel in a laptop bag.

In short, it is easy to recommend if you want a quiet, light mouse to carry around, or one mouse that can switch between two devices. It is not a good fit for gamers or for anyone who wants a rechargeable mouse.

Sensitivity switches between five DPI steps: 800, 1200, 1600, 2400 and 4000. With silent switches and a symmetrical shape, it also works for left-handed users and for people working in shared spaces.

As of September 30, 2026, it was rated 4.4 out of 5 stars from 144 ratings on Amazon.co.jp.

That is not a large sample, but the rating is steady. This article focuses on what the spec numbers mean in daily use and where you need to accept trade-offs.

What the Specs Mean in Practice

At 9.91 cm long, it is a size smaller than the roughly 11-12 cm typical of desktop mice.

With a palm grip, where your whole hand rests on the mouse, users with large hands may find their fingers overhanging. Fingertip and claw grips suit it better.

Users with smaller hands should be comfortable even with a palm grip.

As a rough guide, 1200-1600 DPI feels natural on a single Full HD screen. On a 4K monitor or a dual-screen setup, 2400-4000 lets you reach the screen edges without big wrist movements.

If none of the five steps feels right, fine-tune it with the pointer speed setting in your OS. Also note that an AA battery weighs a little over 20g.

Whether the listed 58g includes the battery changes how the mouse feels, so check the product page if this matters to you.

Compatibility Guide

The mouse connects over Bluetooth or through a 2.4G receiver.

The receiver stores inside the mouse, so it is hard to lose while traveling. As the product name says, it is meant for desktop PCs, laptops and Macs.

Basic functions (pointer movement, clicking and scrolling) work without installing a dedicated driver.

The most common mistake is buying it for a recent USB-C-only laptop or MacBook. Check the receiver's connector type on the product page.

If it doesn't fit, simply plan to use Bluetooth from the start. On the other hand, a desktop PC without Bluetooth depends entirely on the 2.4G receiver.

If the 2.4G connection drops, move the receiver from a rear USB port to a front one, or use an extension cable to bring it closer to the mouse.

Spots right next to USB 3.0 devices or on metal desks tend to make 2.4GHz signals unstable.

On a Mac, adjust scroll direction and pointer speed in System Settings.

The sensor type is not listed. Many optical mice track poorly on glass or high-gloss desks, so using a mouse pad is the safe choice.

Product Info

On Amazon.co.jp, the price was ¥7,509 as of September 30, 2026, sold and shipped by Ｂ＆Ｂストア.

Prices change often, so check the product page for the current price before buying. That is on the high side for a small AA-powered mouse.

Products like this often vary in price by seller and timing, so compare sellers and prices before you decide. The eBay entry only links to search results and has no captured price.

As of September 30, 2026, it was rated 4.4 out of 5 stars from 144 ratings (88% as a score).

The sample is small next to best-selling mice with thousands of ratings, but a steady mid-4 rating suggests no major pattern of early failures. Check the seller page for the release date, warranty period and what is in the box (for example, whether a receiver and battery are included).

This is a practical everyday wireless mouse, not a gaming mouse. The color is dark gray, as the listing states.

It is easiest to judge as a product built around three things: quiet, light, and able to connect to almost anything, rather than raw performance.

Who Should Buy

① Mobile workers who use a laptop on the go: At 58g and this compact size, it slips easily into a bag, and Bluetooth means you don't have to plug in a receiver. The silent switches let you click freely in cafes, meeting rooms and on trains.

However, its DPI and button count fall short for gaming, so FPS players should look elsewhere.

② Users with small hands: The 9.91 cm body is easy to hold, and 58g keeps fatigue low in long sessions.

Users with large hands who palm-grip may find it cramped.

③ Office and home workers who want a quiet mouse: Muted clicks help when you don't want to disturb colleagues or family. It is designed to run a long time on a single AA battery.

It is not rechargeable, though, so you will need to swap batteries.

④ Left-handed users and households that share a PC: The symmetrical shape works in either hand, so a family sharing one PC doesn't need separate mice.

⑤ People who switch between two devices, such as a PC and a tablet: You can pair one device over 2.4G and the other over Bluetooth.

It suits anyone who wants one mouse instead of separate ones for a desktop and a laptop.

Before You Buy

It is not a gaming mouse. A 4000 DPI maximum looks close to gaming territory on paper.

However, the polling rate and sensor model are not listed, and the silent switches have a soft feel. If you need fast repeated clicks or precise aiming in competitive games, you will be happier with a gaming-focused wireless mouse.

Battery power cuts both ways. Swapping in a fresh battery instead of waiting for a recharge is a real advantage on the road.

On the other hand, you pay ongoing costs and have to replace batteries. No battery-life figure is published, so don't count on it lasting months; carrying a spare AA is the safe move.

Silent switches are a matter of taste. Silent switches usually have a weaker click and a softer, sinking feel than standard ones.

If you like a crisp, clear click, they may feel underwhelming. Also, 'silent' refers to the clicks; the scroll wheel may still make some noise.

It has four buttons. If you map browser back/forward or editing shortcuts to side buttons, check the button layout in the product photos.

It is not suited to button-heavy workflows.

It doesn't work with two devices at once. You can keep both Bluetooth and 2.4G connections paired, but you switch to one side at a time rather than controlling both together.

Check the manual for how switching works (a switch or a button).

Check the price and seller. ¥7,509 as of September 30, 2026 is high for an AA-powered mouse in this class.

The same item can appear from several sellers, so compare seller and price before you buy. Because the product name is long, confirm the model by its photos and title so you don't end up with a different color or a similarly named model.

FAQ

Q. Does it work with a USB-C-only MacBook? A.

Yes. Over Bluetooth it works without any adapter.

If you want to use the 2.4G receiver, check its connector type and get a USB adapter if needed.

Q. How long does the battery last? A.

It is described as power-efficient, but no specific runtime is published. Battery life varies with usage and connection type, so keeping a spare AA battery is the reliable approach.

Q. Can I use it for gaming? A.

It handles browser games and casual titles fine, but it is not suited to competitive games such as FPS. The four buttons and the feel of the silent switches are the limiting factors.

Q. Is it completely silent? A.

Silent switches greatly reduce click noise, but the mouse is not totally silent. Think of it as quiet enough not to bother anyone in a quiet office or library.

Q. Can I use rechargeable NiMH AA batteries? A.

They often work in AA-powered mice, but we could not confirm whether the manufacturer officially supports them. Check the battery requirements in the manual before using them.
