Je n'en suis pas à min premier trackball et c'est le meilleur que j'ai testé jusqu'ici. J'aibde grandes main mais sa taille reste très bonne. Sans fil ou avec tout fonctionne bien et les boutons supplémentaires s'avèrent très utiles.

Esta es la segunda vez que compro el trackball, se descompuso la rueda , ya no detectaba el sensor de moviemiento, me duro 3 años, trate de usar otro pero ya estoy super acostumbrado a este tipo. Para el uso de autocad es excelente, programando los comandos F3 y F8 es muy comodo, tambien si tienes rutinas, tipo lisp, puedes agregarlas a los botones programables. Una de las desventajas es que le dura poco la pila, tambien con el tiempo, un año, hay que cambiar los rodamientos de la bola. Lo recomiendo mucho.

【使用シーン・購入目的】 Premiere Proなどで動画編集を行う際、マウス移動の手間を減らしたくてトラックボール型を探していました。 長時間編集でも疲れにくく、ショートカット操作を指元だけで完結できるモデルを求めて購入しています。 【良かった点】 動画編集との相性が抜群です。 8ボタンをショートカットに割り当てることで、再生／停止・カット・タイムライン移動といった操作が指先だけで完結し、編集テンポが大幅に向上しました。 カーソル移動に腕を使わないので、長時間の作業でも肩・肘・手首に疲労が出にくい点も助かります。有線／2.4GHz／Bluetoothの3方式に対応しており、機器の切り替えが柔軟にできるのも地味に便利です。 【気になった点】 右上のボタンは位置的に押しにくく、意識しないとトラックボールに触れてしまうことがあります。 特に手が小さい方は押し方の工夫が必要です。 ただし、使用頻度の低い機能を割り当てるか、押しやすいボタンに主要ショートカットを振り分ければストレスは軽減できます。 【総評】 “作業効率を上げたい編集者向けマウス”として強く推せるモデルです。操作の集中が途切れず、編集のリズムが崩れないため、慣れてくるほど効果を実感できます。 ボタン配置に若干の慣れは必要ですが、それを補って余りある利便性があります。 動画編集・画像加工・DTMなどコマンドを多用する作業との相性が非常に良く、長時間作業の快適さと効率アップを同時に求める人にとって満足度の高い1台でした。

I use the computer for navigating the internet & as a photographer. My hands are pretty large 8" & 1/4. I have always had problems with hand cramps because I have to hold the mouse in sort of a pinch position. For many years I was in love with the original Microsoft big track ball (2010) but they were discontinued so I have been searching for something similar for quite a while. So far this has been a great alternative. I use Lightroom & Photoshop almost daily, sometimes up to 10 hours a day along with a Wacom Tablet for detailed editing but I never liked the Wacom for navigating the internet or programs. The Def Pro has solved all my problems with cramping since it completely changes hand movement. I don't have to pinch the mouse to right & left click because the device comfortably fits in my palm with my fingers relaxed. The thumb becomes the left click, the middle finger becomes the right click & because of the track ball design I can rest the heel of my hand on the desk comfortably. The ball is precise but only as accurate as your finger dexterity. I actually had to slow the speed down a bit. There has been no jumping, stickiness or drag to the ball at all. The thumb wheel is more precise to input than most mice I have used & I have used quite a few. While navigating a page you can scroll back & forth for up & down or tilt the wheel up & down to go right & left. It is a bit tricky downloading the (foreign language) instructions but with persistence & guessing it's not that difficult finding the English version. The mouse works fine out of the box, even with Windows 10 but downloading the Mouse Assistant allows giving the buttons specific operations or changing the function of them. Once you are in the Assistant, it's very simple to use. I'm not a gamer so I have no complaints about the functions available. The only problem I have is that the mouse doesn't wake up after the computer goes to sleep but that may be something to do with the fact that I am using Windows 10 & this device is advertised for Windows 11. I did figure out a workaround of just unplugging the USB plug momentarily which wakes up the mouse which is fine until I upgrade to Win 11. Overall I gave this device 5 stars because it works as advertised & better than several alternatives I tried previously at different price points. I'm not a heavy gamer but I am a heavy mouse user & this item seems to be a good value for function, quality & price. I would definitely buy again or try other ELECOM products.
