Riracon

Perfetto per fare Cyclette e lavorare contemporaneamente. È possibile regolare la sensibilità della sfera per il puntamento, dopo un po' di pratica è un mouse ottimo.

Le prix vaut le coup pratique à utiliser et il fonctionne bien avec un adaptateur USB sur un smartphone Android

Ma copine ayant une tendinite à l'épaule, cette souris convient parfaitement car elle n'est plus obligée de lever le bras. Elle est légère et ergonomique. Bien penser à avoir un adaptateur bluetooth et installer le logiciel ELECOM pour paramétrer la souris comme il faut.

So this things great. It takes some weeks, but when you get used to it, its just marginally less functional than the best mouse you had (there are some minor things that were sacrificed for the design to get this good, e.g. its not that easy to drag and scroll at the same time) Its much more healthy to use it and it gives freedom of movement. better than my most optimistic guess on how good it will be. For buyers my two advices are: buy this thing, but dont pay extra for the little stand, its not good and even if it were, its unnecessary. There are 4 things for product designers, thats been bothering me: -the ball is 25.0mm, the hole is 25.4mm. this makes the ball move and jiggle when turned too much. This means that when you pick it up, or you remove your finger from the ball when not upright, the cursor moves a bit. its annoying. as someone else said a 1inch ball bearing functions better than the high-end trackball, but you have to hunt for the right one (no acid resistant e.g.), so the two frictions are right -the material is a bit light and flimsy, the feel would be better if it were heavier and a bit more rigid. also with the loose ball the sound and feel are a bit cheap for such a great product -the battery door opens the wrong direction. it doesnt happen often, but it can open during usage. you never push your under-fingers, but sometimes you pull them to counterbalance your controlling fingers. this problem and the one before could also be helped by having 2 sizes, if my hands were smaller these wouldnt be this noticeable. -id prefer to switch right and left click. i imagine most people dont, but its not comfy to switch for whoever wants to. if the buttons were more similar sizes, like 15% change, i could switch comfortably. But you can imagine how good this thing is if these are my worst complaints with a product that people buy with the mindset "funny idea, i wonder how bad it is in practice". get ready to be surprised.
