I’m not the person you responded to, but I’ve owned several thumb trackballs and my favorite is the Logitech MX Ergo Plus.

The “Plus” version is the same as the normal “MX Ergo” but with an optional angled support provided (and only available in the US, I imported mines from Ebay).

Thank you, I saw the pictures that the trackball mouse and I wonder whether they are quite large in order to accommodate the trackball as I have a small palm(dwarfism).

The dimensions[1][2] when compared to standard mouse(e.g. M275)[3] seems to be about an inch higher(height, width), Also the GP comment says Ploopy was a bit large to use; Are the thumb trackball mouse inherently larger?
