Learning Proposal: Standalone 3 Inch USB Trackball Matches Tankstick / Tankstick Max Trackball

Reusable Rule

When a customer asks whether the standalone 3 inch USB trackball assembly is the same type used in the Tankstick or Tankstick Max, support can answer that it is the same trackball used in those units and is suitable for that style of DIY build.

Evidence

In ticket 31058, the manual public reply stated: "The trackball we are selling is the exact same one used in the Tankstick and Tankstick Max, so it will work great for your project."

Drafting Guidance

Answer the compatibility/fit question directly. Avoid claiming a third-party OEM or brand name such as GRS unless current inventory confirms that specific batch/brand.
