ProtoArc EM01 NL トラックボールマウス 静音 20°角度調整 無線 2.4G Bluetooth対応 3台同時接続 手首負担軽減

1年以上じっくり愛用してのレビューです。定番機種であるロジクールの「ERGO M575」と比較しながら、実際の使用感を共有します。 結論から言うと、細かなカーソル速度の微調整に強いこだわりがなければ、M575よりも安価で非常に満足度の高い選択肢になる優れた製品です。 ◆ カーソル操作と「ボールの転がり」の特徴 ロジクール製品と違い、専用ソフトによる細かなマウス速度の微調整はできませんが、挙動のカクつきや速度の異常などは一切なく安定しています。 M575のようにボールを勢いよく弾いて「シューッ」と長距離を移動させるような慣性操作はできませんが、狙った位置へのカーソル移動は慣れればしっかりとコントロール可能です。操作自体もそこまで時間をかけずに馴染むことができました。 ◆ 優れた角度調整機能と心地よい静音クリック 本製品の大きな強みは、本体の角度を調整できる機能です。手首に負担のかからない自然な角度にセットできるため、長時間の作業でも疲れにくいです。 また、クリックボタンは静音仕様になっており、押し心地がとても良く静かな場所でも気兼ねなく使えます。クリックの深さは左右ともに比較的浅めですが、意図せず触れただけで誤クリックしてしまうようなことはなく、絶妙な調整だと感じます。 ◆ サイズ感とスクロールホイールの操作性 通常のマウスに比べると大柄なサイズですが、ホールドした際の違和感はありません。私は手が小さい方ですが、ボタンやボールの配置も含めて問題なく快適に操作できています。 スクロールホイールの操作感も硬すぎず柔らかすぎずで文句ありません。表面に滑り止めのグリップの凹凸（スリット）が施されている点も扱いやすくて良いです。 ◆ 【唯一の不満点】M575と比べたメンテナンス性 ほぼ不満のない製品ですが、M575と比較すると、内部の支持球にゴミが溜まりやすいのか、ボールの清掃が必要になる回数がやや多いように感じます。しばらく使うとボールの滑りが少し重くなりますが、定期的に取り外してサッと掃除をしてあげれば、すぐに元のスムーズな操作感に戻ります。 ◆ 総評 価格を抑えつつ、角度調整や静音クリックといった機能を求めている方には、非常にコストパフォーマンスが高いおすすめのトラックボールマウスです。

必要充分な機能とトラックボールの安定性があります。 logicoolのトラックボールと迷いましたがトラックボール自体が初めてだったのと形状がほぼ同じだったためこちらを選択。結果必要充分な機能でトラックボールの恩恵を受けられていると思います。3dプリンターで追加で角度を25度ほどつけるバンクを足して、ボールの位置がほぼ上方にくるようにカスタムして使っていますが、手が楽になったと思います。作業の内容によっては細かな動きはマウスが必要になる場合がありますが、大枠ではこれで賄えています。一点あるとすれば横スクロールのための機能があればより良かったかなとは思いますが概ねコストパフォーマンスがよく、買って良かったかなと思います。

某大手メーカーのトラックボールマウスに似たマウスです。 トラックボールに慣れるためにと思い、購入しました。 値段はめちゃくちゃ安いけど、問題なく使えてます！ コスパ最高！ さすがに外では使えませんが、家で使う分には十分すぎるくらいです。 買ってよかった！

マウスの上側に接続先切り替えボタンがあるので大変便利。 よく手に馴染むので使用感も大変良い。

購入して２年近く経ちましたが、不具合などは一切無く快適に使えています。 購入当初、本体を掴んでる際、薬指に力が入ってしまって意図せず右クリックが作動してしまうことが頻発しましたが 慣れてくるとそれも無くなりました。

操作は問題なく動来ます。 ただ、スクロールの行の横移動がなく、 ポインターのスピード調整のボタンを謝って触れやすい所にあるので、PC本体のスピードを下げて、使用しています。 次回購入は微妙です。

3つのデバイスと接続切り替え可能で気に入って使っていたのですが、2カ月でホイールが予測不明のスクロールをするようになり、ストレスが溜まるので捨てました。やはり高くても信頼性の高いものを選ぼうと思いました。

トラックボールは少し引っ掛かりは感じるものの、全体的には手に馴染み使用しやすいように思う。 ただ、使用して半年ほど経ち当然反応しなくなった。 特に落下させたことはない。 充電ランプは反応するがそれ以外は反応せず、Bluetoothボタンも反応しない。マウスも動かない。

Ho acquistato questo mouse come alternativa al Logitech Ergo che utilizzo ormai da molti anni. Dopo 3-4 mesi di utilizzo, sono totalmente soddisfatto. Se avete già usato Logitech Ergo, ecco alcune differenze e punti notevoli. a) la base è di plastica (anziché metallica) e si può regolare su due posizioni, quindi risulta più leggero, ma stabile b) il fondo della base è antiscivolo, discreta aderenza c) può essere collegato a 3 diversi apparati via Bluetooth, si cambia rapidamente col bottone selettore, molto comodo d) l'inclinazione della base è minore rispetto ad Ergo, ma ancora comfortevole e) la precisione del puntatore è più che soddisfacente f) si ricarica tramite USB-C, ci vogliono alcune ore - quando è in carica c'è un led rosso acceso, che si spegne a carica completa. Dato il costo significativamente minore, direi che è un ottima alternativa al prodotto Logitech

I've been using this daily now for almost a year and I find it much more comfortable to use and easier on the wrist than a regular mouse. I bought it to try because I was feeling strain from clicking and holding the middle mouse button whilst also moving the mouse which you have to do a fair bit in Blender and other 3D software. This type of mouse solved my problem as I'm no longer fighting my own grip. It's also a space saver as you no longer need to move the mouse around the desk. This is my first trackball mouse but I quickly adapted and within a couple of days I was just as accurate at moving the ball as I was pointing with a regular mouse. I don't have much to compare to but the build quality feels solid. I've not had any connectivity issues or issues with glide or smoothness, and it works well switching between different devices. The battery lasts a few months between charges and you can use it while charging too. The buttons are all nice to click in both orientations (flat or tilted) and the sensitivity is just set once and forget. You do have to pop the ball out to remove dust occasionally but it appears that's just expected maintenance with this kind of mouse. There's a handy hole you can push something through to help with popping it out. I'm really happy with this purchase and it has become part of my every day setup. I'm not sure how it weighs up against more expensive models but I'm happy enough and not looking to upgrade any time soon.

Such a game changer for working on my laptop at a small desk! I use this for my online assessments, Word, excel worksheets and it is nice not to have to move my hand all over the mouse pad. Easy with games that don't involve heavy combat and perfect for Baldur's Gate 3 and other turn based fighting. Two months and its still my favourite mouse.

TL;DR This is a premium mouse. It is great for CAD and graphic design, and also good for gaming and daily use. I know this is a bit intangible, but, it just feels like a quality mouse in your hand and has all the features you would expect from a premium trackball mouse. So I don't say something is a premium device lightly. Right from the start, before you even touch the mouse you know you're in for something special. There is pride put into even the packaging and presentation as you unbox it. First, I have some big hands, and it fits me well, and my wife has small hands and it works well for her too. the clickable area is about 2 inches long. it hits that sweet spot on size and button postion. The feel of it is great, I like that the angle of the trackball mouse can be changed from 0 to 20 degrees so I can set it to fit more naturally to my hand position when lying across a desk. This leads to less fatigue when using the mouse for extended periods with gameplay or CAD work. The mouse button clicks are nearly silent but with good tactile feedback, so this is great for office work, or at home where you don't want to disturb anyone. this mouse will not wake my wife :) I like that I can use this with multiple devices, using either the included dongle or Bluetooth. You can switch between devices quickly from the top. This is a big deal to me as one of my pet peeves with my other devices is that I ahve to turn it over to switch between devices. Changing the mouse sensitivity / DPI is also done just as easily from the top of the mouse. these two features are productivity multipliers. it says the charge lasts 300 days on Standby. I can't say yet how long a charge lasts in day-to-day use, but it sounds like it will last a long time. They don't say what standby means, does it mean off, or on but not used? I am not worried about it but I do wish the battery lifespan information was more relatable to usage time. Things I wish were better... Now do keep this in mind, I like the trackball mouse, but like anyone, there are always things you wish were different: for me, if it was jsut a little big heavier that would be nice. not that it moves around, i just like a bit more heft to the base. I would have liked it if there was a place to store the dongle on the mouse. it is always nice to ahve a spot for the USB dongle when you are not using it so it doesn't get separated/lost. I wish the angle was adjustable not just 0 and 20 degrees. I wish the mouse worked as a USB mouse also. I wish there was a left-handed version. Although the basic instructions are in all languages, I do think they should have detailed install instructions and images in all languages not just Chinese. None of these things are problems for me, but at least you know before you make a decision. Overall, I find this mouse to be very flexible, allowing me to easily change between 3 devices quickly and change the DPI on the fly. This is a great trackball mouse with features I find indispensable.
