I never thought in my lifetime I'd witness a trackball that surpassed my old Logitech in value, comfort & performance. I was wrong. I don't think I've ever used a smoother-feeling, more precise trackball than the Sanwa. Given its use as my daily driver, it is comfortable to use and performs well, with the DPI settings being welcome functionality. Read more

I'm not a hundred percent impressed with this. It works, but sometimes it seems the mouse pointer on the screen jumps slightly when trying to make small adjustments, so it's not smooth. Also, I wouldn't say I like the speed adjust on top of the mouse, either. Kids push a button, and I always have to reset it. Lastly, my computer does not recognize it when I restart. I generally have to remove the wireless USB plug and put it back in. However, this could be my computer, although I didn't have trouble with the last one. Read more

I loved this product from the moment I saw it. Somehow, am object shaped as a lump of clay [do it fits our hand, big or small], managed to look graceful, and work flawlessly. The trackball. Would still be by my computer side, if my wife did not spot it and confescsted it. Too beautiful and too useful, she said. I only wish I could have it in a left-hand configuration. Not only I am left handed, but my right hand is not stable enough. I purchased another Brand's left handed trackball, but it is not nearly as smooth, pretty, nor comfortable. Read more

I thought I was losing my mind. I play online video games (FFXIV anyone? XD) and do graphic design on the side using Illustrator, InDesign, and so forth. I got this mouth to replace one that was becoming harder and harder to control but this became worse. Day 1 was beautiful, but ever day after that it didn't matter how often I cleaned the rollers, it was like my hand was too heavy for the ball! It would catch and jerk around the screen. I purchased a cheap ass Logitech and have not had the same problem at all. I will say this is super quiet and super soft though. I really wish it wasn't so... sensitive? I don't know why it's roller just won't work. When I say it jerked around, I mean I couldn't properly click 50x50 icons. It was a course correction event to do so. With InDesign, there is a baked in 'catch' to help the designer orientate objects. This mouse fought that like it was religiously opposed to delicate fine movement. I lasted 4 days with this mouth before buying its replacement. My partner threw out the box so I guess it's my last ditch emergency mouse now. Read more

I went ahead and pulled the trigger on this based on the Sanwa name from experience with their arcade equipment. Very pleased with what I got, it works very well and I am happy that I didn't have to shell out a bunch more for the Logitech model. Read more
