Review: トラックボールに慣れると手が本当に楽。省スペースでも快適 - 初めてトラックボールマウスを使いましたが、想像以上に快適でした。 親指で操作するスクロール（ボール）は、最初こそ少し戸惑いますが、慣れるとページ送りや細かい移動がとてもスムーズで、通常のマウスよりも楽に操作できます。 マウス本体を動かす必要がないため、手首や腕への負担が少なく、長時間のPC作業でも疲れにくいのが特に良い点です。 デスクのスペースも取らず、狭い場所やソファなどでも問題なく使えるのは大きなメリットだと思います。 これからさらに使いこなしていけば、作業効率ももっと上がりそうなので、長く付き合えるマウスになりそうです。
Review: 初めてのトラックボールに、右利きの人でも大丈夫！ - 初めてのトラックボールマウスとして購入。 当方右利きでいままで右手でマウスを使ってましたが、多ボタンのトラックボールをお絵かきソフトの左手ツールとして使える可能性を見出し購入しました。結果マウスの代わりとしても使いやすく、左手ツールとしても使えました。 普段使いするだけなら1週間もかからずに慣れましたが、個人差はありと思います。ボールは社外品に変えたという意見もよく見ましたが、とりあえず使うだけなら不要だと思います。動かしてて安っぽい感じはするのでこだわる人は変えた方がいいかもしれません。

## Questions & Answers

**Q: Do you have left handed **wired** track ball mouse? Just like the wireless one here (I have two of them)**
A: Yes but I have to change batteries every 3 months also, I have to press the right button which is for enter all the way down to the bottom. I don't like it. I will replace it as soon as I can find a reliable one.

**Q: If I program this mouse on one computer on one computer and then use it on another computer with the programming saved?**
A: To my knowledge you cannot 'program' this mouse. You can configure it, such as button function, but that is done on the computer via the driver settings.  If you moved the trackball to another computer, those settings would have to be done done again.

**Q: Is the red ball the red ball, the newer more accurate replacement ball, or just simply colored red? Sorry if I missed it in the prior answers. Thanks!**
A: It says in the product description that current optical recognition technology is more accurate with the red ball.

**Q: How long battery last**
A: I never turn the switch on the underside of the mouse off. I use this every day for work (7-10 hours). Lasts 2-3 months easily. I don't feel like I have to change batteries often at all.

### ⭐⭐⭐⭐ 初めてのトラックボールに、右利きの人でも大丈夫！
*by エ***ス on November 5, 2025*

初めてのトラックボールマウスとして購入。 当方右利きでいままで右手でマウスを使ってましたが、多ボタンのトラックボールをお絵かきソフトの左手ツールとして使える可能性を見出し購入しました。結果マウスの代わりとしても使いやすく、左手ツールとしても使えました。 普段使いするだけなら1週間もかからずに慣れましたが、個人差はありと思います。ボールは社外品に変えたという意見もよく見ましたが、とりあえず使うだけなら不要だと思います。動かしてて安っぽい感じはするのでこだわる人は変えた方がいいかもしれません。

### ⭐⭐⭐⭐⭐ いいねえ
*by た***ん on January 28, 2026*

右利きですがマウスは左です。 コスパ良いのを探してました。 これより安いのを見たことがありません。 2年以上使っていますがメンテナンスすれば一生使えそうです
