GameBall

Personally, I think this would be the goal for the trackball.
- The exposed area of the ball is justified.I can fine-tune it with two fingers and take large finger strokes.
- The touch sensor for scrolling is still useful.I personally like having horizontal scrolling.
- No special drivers or software are required, the hardware is complete, the PC recognizes it as a standard other-button mouse, and all settings can be made in the mouse hardware, so there is no need to worry about stopping software updates in the future.
- The buttons are a bit stiff, and right-clicking takes some getting used to.I preferred the MarbleMouse here.
- It takes some getting used to, but sometimes the scrolling moves with the finger touching it.Might adjust the area of the touch sensor with tape or something in the future.

I have been using it for playing mainly FPS and RTS games as well as using it for work with processing audio and 3d modeling. I got used to it during a week despite it being my first finger trackball. The ball is very smooth and I don't notice any static friction which would impede precision in meaningful way, despite it using static bearings. Additional horizontal scroll is useful addition.

Gaming-wise I am able to play old school arena shooters and complete stalker 2 on gameball, it is perfectly suitable for any genre IMO, especially if one is willing to take time to adapt. It is good with or without acceleration depending on your preferences. I use acceleration, specifically tuned to provide my usual sensitivity at fast movement, and more precision during slow ball movement. This way I do not overshoot and able to be precise despite having small aiming 'surface.'
It is also excellent device for portable gaming with laptop (or docked handhelds), since trackballs negate requirement for space unlike mice.

One small thing, out of the box there was issue with 'back' button (mouse 4, top-left) due to which the button would become stuck after press. To resolve it I decided to disassemble the device, but really all it was is over-tightened bolt at the front of the device, super easy fix. After that the device is pretty perfect. Really hope that Pro version will have the same or better level of smoothness.

I would recommend it even as a first ever trackball, especially for people who value ergonomics, but do not wish to compromise gaming.

Very smooth and precise. Feels great playing FPS!

I had an Elecom Huge that has failed, which worked OK after a lot of modification. I was hoping the Gameball would fix those issues. It did, BUT

The picture of the device had a physical scroll wheel in the middle. The device I received had a touchpad immediately adjacent to the ball well for scrolling. This thing is poorly implemented. You cannot control the amount it scrolls (or which direction) easily. Worse, if you finger touches the mouse while moving the trackball ball, it hits the touchpad and scrolls (in games this typically changes weapons). It driving me nuts

If this was $35 or less, it would be a minor gripe. For a $200 device, this is unacceptable.

I’ve owned multiple trackball mouse’s for gaming but the Gameball is hands down the best! It’s molded to fit your hand perfectly, All buttons are easily accessible and the trackball is so smooth and placed perfecly. 10000/10 reccomend!
