GRS LED Trackball with Spinner for Arcade

I bought this with the intent to use with my Rasberry Pi. I have a 128GB image that covers several emulators. When I received the unit, I found it to be very well built and packaged. The trackball, although small, rolls smoothly and is accurate. The spinner is especially nicely weighted and spins for days. The only emulator on my Rasberry Pi, that recognize the trackball and spinner out of the box is MAME. I contacted Thunderstik customer service who provided a nice youtube video that explained how you can change control options in Retroarch. This process is done in the Linex code and is not as simple as plugging in the USB trackball and spinner to map the controls in other emulators (Nintendo, Atari, Sega etc).

Pretty good, however switching the dip switches to all white… is still blue/greenBatocera on my raspberry pie 4 had no problems with this trackball/spinner.

Works great on arcade board from China. Nice to have a trackball as well as a spinner.

I needed a 3" trackball, but the harness with the trackball and spinner are excellent quality and formfactor.

This is simply put, an absolutely awesome trackball/spinner combination package!!!Works fantastic with my Pandora 516 in 1 Vertical Cocktail Arcade Table. Top Notch!!!

Not sure if I got a bum unit, or if they are all like this, but the trackball has a rough feel when spinning, and is not very free spinning at all / stops spinning quite quickly.

worked great, it was very accurate as well. super simple to install and a great product for the price
