Review: 〇角度がついていてよかった。 〇トラックボール、クリック、手触り、申し分なし 〇マウスとしては申し分なし 〇前面で切り替えできるので裏返す必要なし △USBレシーバーの保管するところがほしかったかも
Review: 約4年前からずっとロジクールのM575を家用と仕事用と2台使っています。 M575はとても使いやすく、乾電池仕様ですが、使い方にもよるでしょうけど1年ぐらいは長持ちするので、充電するものより使い勝手がよくて重宝していました。4年間2台とも壊れることもなく、家用の方は裏面のゴムが順に剥がれてきたのですが、接着剤で付ければ問題なく使えていたので、とても満足度が高かったです。 しかし、ここへきて家の方のPCを追加したことで3台切り替えて使わなければいけなくなり、M575は無線とBluethoothで切り替えて2台は使えるものの、3台は無理なのと、切り替えも本体を裏返してスイッチを押さないとできないので、結構悩みましたが、思い切ってこちらの商品を購入しました。 トラックボールの動きはM575との比較では遜色なく、ただ若干買って間もないからか、複数文字の選択がしづらいというか、ちょっとしたずれを感じます。でもM575も最初はそんなだった気もするのでこれだけで劣っているとは言えないいかもですね。こちらにはDPIの変更があるのは普通に便利ですし。 クリックは静音なのでクリックした感がなくてまだ慣れないですが、ホイールの音は多少カチカチ音がするものの、私のM575も古いからか似たような音がしていたので、そこは気にならなかったです。 これで耐久性が良ければ言う事なしだと思います。結局はそこに尽きるかと思います。 少し前にはWindowsはアークマウスでMacはマジックマウスを使ってましたが、それらは値段も高く、M575もこの商品より高いですし、最近は高いマウスが多いように思います。 その分性能もいいのでしょうけど、この商品が２，３年もってくれるならの前提ですが、消耗品と考えるとマウスは本当はこのぐらいの値段がいいですね。

## 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). Try USB and Bluetooth.Also check the Bluetooth version of your device. Depending on the Bluetooth version, it may be a little delay.Bluetooth 3.0 or below cannot be connected.

**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. The outlet is made quite compact, so please connect the included USB Type A & C cable to charge.Not compatible with Type C & C cables. 3. With energy saving mode, if the mouse does not operate, you can sleep and reduce power, click the mouse many times or turn the ball several times to wake it down.

**Q: 2. Please be careful after purchase.**
A: 4. A little bit larger and heavier than normal mouse, so it is a little unsuitable for carrying. 5. If you do not use it for a long time, please turn the power button on the back to "OFF".Fits right hand 6. Store the USB carefullySmall so please do not lose it. 7. Regular cleaning is required as the roller and post that holds the ball and ball is easy to collect dust. 8.
