## Description

desertcart.co.jp: ProtoArc EM01 Trackball Mouse, NL, Supports Both 2.4G and Bluetooth, 3 Devices Simultaneously Connected, Wireless Mouse, 5 Levels of Adjustment, DPI, 7 Buttons, Trackball Mouse Wireless, Compatible : Computers

Review: 売れ筋のロジクールM575も所有しているが、ボールの動きの良さはほぼ互角に感じる。 左右クリックは静音で若干軽い感じはあるものの、慣れてしまえば全く違和感が無い。 スクロールホイールの動きと音が少々気になるが、個体差もありそうでこちらも評価を落とすほどでは無い。 チルト角度の2段階調整も便利で、MX ERGOをほぼ再現し、不用意に切り替わったりもしないので作りは良い。 ただ、底面は金属ではなく恐らくプラスチック製で安定感は若干劣ると思う。（MX ERGOは試しに使った程度なので厳密には分からない） 3端末切り替えスイッチも程よい場所にあり、ストレス無く切り替えれる。間違えて押してしまうことは一度も無かった。 ロジクールのように専用ソフトウェアがあれば完璧だったかもしれないが、この価格で機能的には十分過ぎる。コストパフォーマンスは圧倒的。 普段はこのトラックボールマウスと「Edifier HECATE G3M PRO」という静音ゲーミングマウスを使い分けている。 ロジクール M575は予備で置いてあるが、トラックボール初心者にはM575を薦める。M575で馴染まなければ、恐らく他のトラックボールも馴染めないはず。それほどまでにザ・スタンダード。 ProtoArc EM01 NLは、トラックボールマウス中級者以上があえて選ぶ製品という印象。もちろん、これを最初に買っても損はないくらいにクオリティは高い。
Review: 自宅用に導入しました。総合的にとても満足しています。 まず3台のデバイスに同時接続（2.4G／Bluetooth）できる点が便利で、私が使用している2台のPC間の切り替えがボタンひとつでかなりスムーズ。待ち時間もほとんどない。USB-C充電式でケーブルの煩わしさがなく、長時間のPC作業でもバッテリー持ちも良好です。静音設計なのも集中作業に向いていて良いですね。 角度が付いている形状は手首への負担が軽く、長時間使っても疲れにくいです。人間工学的にもよく考えられている印象。 ただ、星を1つ減らした理由としては以下の2点です。 ・倍以上の値段のロジクールのトラックボールと比べると、ボールの転がりがほんの少しだけ引っかかる感じ（カリカリ感）があり、極上の滑らかさには届かないところ。とはいえ価格を考えれば十分滑らかではあります。 ・この価格帯でチルトホイール（横スクロール機能）が付いていたら最高だったと思います。縦スクロールは快適ですが、横スクロールがないと用途によっては不便に感じる場面もありました。 総合すると「コスパの高いトラックボールマウス」で、特に価格・使いやすさ・接続の柔軟性を重視する人にはおすすめです。

## Features

- The EM01NL has evolved further from the EM01. This is an improved wireless trackball mouse that has been updated from the popular ProtoArc EM01 trackball mouse, which has been referred to as SNS such as Facebook, Twitter, and Youtube. P1 (LED illumination leads to wasteful battery consumption), so after considering that the LED ring on the ball mouse will not light up, the battery has been extended by making sure that the battery has been used. The P2 DPI has been updated from 3 stages of 1000, 1600, 2400 to 5 levels of 200, 400, 800, 1200, 1600, and you can adjust the speed of the pointer by hand. According to the feedback of the P3 (Trackball Scratches on the main unit), we repeatedly modify the inner housing, seeking a smooth maneuverability. Point 4. The Bluetooth version on the mouse is also updated from 4.2 to 5.0. The connection is more stable, and the transmission range is wider, and the battery life is longer
- Adjustable tilt angle trackball mouse Ergonomic thumb-activated trackball mouse with 20 degree tilt positions The ball mouse has a magnetic board on the bottom and can be adjusted from 0° and 20° like the most MX ERGO in the industry. This allows your wrist to be adjusted naturally. This thumb-type trackball is easy to operate without moving the mouse body. Wireless type allows you to position your preferred position even in uneven areas such as above your knee. 34 mm ball: Equipped with a smooth ball, this trackball has a large, smooth maneuvering, and an ergonomic design. If you are working on a computer for a long period of time, we hope you
- Multi-pairing makes it easy to switch between connections. You can connect to 3 devices at the same time as your usual ProtoArc wireless mouse with 1 USB wireless and 2 Bluetooth. Unlike commercially available mouse with a switch on the bottom of the switch, there is a button on the front of the wheel. For customers using multiple PCs, this trackball mouse can be quickly switched with one button. If you want to switch between multiple devices such as your PC, iPad, you can use the button to switch the connection. It also has a stable connection and can be used with any system such as Windows, Android, Mac OS PC, etc
- DPI adjustable precision: DPI switches DPI to 200, 400, 800, 1200, 1600, and this Bluetooth trackball mouse is easy to use. In addition, the two switching buttons are also located on the side of the mouse for easy operation. It also comes with a DPI indicator light so you can see how many levels you have switched to and how many times the light flashes on the side. Compared to regular mouse, the ball operation is smooth, delicate, and speedy so you can expect a lot more efficient work on your computer especially when working with dual monitors. Caution: 1. Please understand that it is not suitable for extremely delicate operations such as games and drawings. EXCELL takes a little bit of time to get used to it. 2. The button can be assigned randomly. ]
- Rechargeable, eco-friendly, rechargeable trackball mouse that does not require batteries. It is equipped with a large capacity of 900 Mah battery that is more durable than commercial batteries; it can be used for continuous standby time of about 300-360 days, and with the included charging cable, it can be used for about 160-240 hours (about 20-30 days). Double the working time of 5-7 days of ProtoArc EM01. It charges very little and requires no need to replace batteries that are the most stressful of wireless batteries. [Caution] 1. Calculated usage time by about 25% of the mouse while using your PC for 8 hours a day. 2. The USB C connector for charging is a little narrow, making sure to charge with the included cable. ]
- Easy to connect Just select the number 1 of the mouse and plug the USB receiver into your device and you can use it immediately. The Bluetooth connection method is clearly explained in the included Japanese instruction manual, so anyone can easily connect it. Note: For Windows 7.0 and earlier, please use the USB receiver. ]
- Excellent silent experience: Logitech MX ERGO, which is more talked about the "M575" and the wheels will not clicking sounds, and the ProtoArc EM001NL trackball mouse has a button that moves the left and right buttons to move forward and back to the button. The silent click type makes it great for use in the office, library, study room, or at home and in environments where you need to worry about sound quality. Note: There is a little scrolling noise, so please consider this product if you are concerned about it
- Wireless mouse that does not require a moving area!️ The rechargeable trackball mouse is smooth and does not need to move the mouse on your desk, so it is extremely small in space. Wireless type with excellent portability. Unlike wired or ordinary mouse, you can operate your computer while relaxing on your desk, sofa, or in the cold, or in the futon or kota, and no mouse pad needed. It is a strong companion for desk work users that can easily be used in narrow spaces
- Easy to clean If the surface of the mouse becomes dirty or slippery, this trackball mouse can be wiped off with cloth, tissue, wet wipes, etc. The small hole on the back side is inserted into a small pin such as a cotton swab to remove the trackball, making it easy to maintain such as replacing or wiping the ball

## Questions & Answers

**Q: The trackball pointer will remain clicking and the ball becomes dragged as you move.**
A: This is likely to enter the "Auto Mode" trackball mouse. Auto mode is to change the cursor position through the ball moving by inadvertently pressing the scroll during use. By moving the mouse up and down, the cursor will automatically move around. Press and hold the scroll foil in the middle to recover.Alternatively, please press the left button or right button. If you have any questions in "Auto Mode" please contact our support.

**Q: Switch between devices and it will not work.**
A: Remove the connection history from your device and connect again. Please refer to the attached Japanese instruction manual (English language not guaranteed).

**Q: Please read carefully before purchasing.**
A: 1. Not suitable for delicate operations such as games and drawing. 2. Forward and Back button: Does not support MACOS. 3. The left and right buttons reduce noise by more than 90% than conventional models, but the silent experience is different, so it is not recommended for those who want a very quiet mouse. 4. No tilt wheel function.There are no special apps to assign different functions to each button, but from the comment of "Mmm", you can assign it freely by using the X-Mouse Button Control software (free) from the comments.

**Q: 1. Please be careful after purchase.**
A: 1. Unlike traditional mouse, this thumb type trackball takes some time to get used to it.Depending on the user's habit and daily usage time, the battery usage time may vary. 2.

*by O***3 on November 24, 2025*

職場でPCを使い分けて作業する必要があったため、複数の端末に接続可能かつ切り替えが簡単なトラックボールマウスを探していました。こちらの製品は接続先の切り替えスイッチが上面に付いているということで、PCの使い分けがストレスフリーになりとても良かったです。操作性も他のメーカーと比べて違和感なく、この値段でこの機能は大変コスパが良いと思います。 が、使い始めて2週間ほどでホイールの挙動がおかしくなり、画面スクロールが思うようにできなくなりました。初期不良かも知れませんが、耐久性はちょっとイマイチなところがあるかも？ メーカーに交換について問い合わせたところ返信は早く、初期不良ということで新品を送ってもらえるとのことでしたが、2ヶ月経った今も製品が届いておりません。また問い合わせみようとは思いますが…サポートに関してはなんとも言えないところです。 2026/2/6追記 二度ほど手違いにより交換品が到着しない事態に見舞われましたが、メーカー様より無償で交換品をお送りいただきました。メールの返信も早く、迅速な対応でとても助かりました。 職場で二週間ほど使用していますが、今のところは不具合もなく快適に使えています。購入前は意識していませんでしたが、マウス本体の角度切り替えがとても効果的で手首に優しいです。この価格でこの機能性はコスパおばけだと思います。オススメ！
