GameBall

Amazing quality. My favorite trackball

After using the logitech marble for 15+ years switching to the gameball at first felt little different having to right click with pinky but after 2 weeks I'm obsessed I love everything about it especially the scrollwheel touchpad and the smoothest trackball
Can't wait for the pro model :)

This is my first experience with trackballs, so not too much to say yet. Build quality is solid, driverless-setup is a nice bonus, comfort-wise seems ok too. Still getting used to it, but on a second week of usage it feels much more natural than on a day one.

I bought the gameball mainly for medical radiology work navigating large stacks of diagnostic images for many hours per day, intending to use the continuous scroll touch pad. It takes some getting used to but as an ergonomic tool for people getting pain from traditional scroll wheels or repetitive click-drag motions with a traditional mouse, the continuous scroll touch pad is brilliant. So for my type of use for the scroll pad I give it 5 stars. Rest of trackball function wise it also seems really good. The button configuration using firmware seems to work really well. Would be great to see a software to do further onboard memory customisation in future - things like click-lock for example. Thanks for creating this product

Ergonomically and technically this ball is as good as it gets. Ergonomically, positions your hand comfortably and in the proper position to easily reach all controls. It has a natural feel with your hand position. The vertical scroll is absolutely the best I have ever used. I am using this track ball in a full motion simulator in virtual reality and the precision is outstanding. The best part for me technically is I needed a peripheral that does not need running software in the background on the computer that takes up CPU space. I have used many track balls and this one absolutely just fits the bill. I am extremely happy with it and very glad that I decided to give it a try.
