Value fee is okay
Works good. I've been using logitech forever. This is just like it. Just insert the usb receiver and turn on the button on trackball. Rechargeable with any usb-c cable. You get one in the package too. Overall pleased..
works perfectly with our Steam Deck (obviously without the D-pad &c). used in the wrong position for long periods makes my hand ache a bit, but some common sense overcomes that no problem
When I first got this trackball I felt it was a little to sensitive, and would have to slow it down in settings. However, I was using it left handed, and I normally use mice and trackballs with my right hand. Furthermore, I got used to this trackball before I got around to changing settings. Another trackball I use is from Amazon Basics; this trackball is considerably less expensive.
Works good better than my Logitech one and more comfortable material
Beautiful quality
rechargeable perfect for long fingers and will make a good gift
When I looked at the box and the cards inside, I felt the attention of manufacturing and high quality. I am also happy to have Japanese instructions. It was the first time I used a trackball by rolling it with my fingers, and at first I felt difficult to use, but I got used to it quickly. It's not good for delicate work that requires fine-tuning (it also writes so in the instructions.) it's like, but maybe I can get used to it...? It is easy because you do not have to move your arm about normal use.
It works out of the box. the right and left buttons feel a little mushy, but for the price I'm okay with it. it's a fraction of the price of a MX Ergo and does the same thing.
Excellent mouse, very good quality
ProtoArc EM04. A very good quality Trackball, it is very precise, the palmar angle is perfect, it is installed quickly.
Very good mouse, excellent quality. It is only necessary to get used to it a little. Great for messing around in places with little space.
An excellent product of marijuana quality and very adjustable, although if I had to say something against it it would be that it does not have an automatic sleep or shutdown mode when the computer is turned off as if it has other mouse
