I was hopeful but dubious that these would work to replace the trackball in my new elecom relacon with 25mm trackball. all of the design information states that the trackball must be as hard as possible to work better. these delrin balls are supposedly a lot lot softer than the specifically engineered one that comes supplied, or the spare that is available for separate purchase at roughly £45. these coat less than £2 each and after using for over a week i can safely say they are sooooooo so much better! forget that red thing, no matter how engineered or "solid" it is. who cares if they as re softer when delrin is self lubricating. why on earth don't they just use these in the industry as the standard? they amazing 🤩 🤙🙌🪇

It’s a ball… it works as a ball. I used it as a replacement trackball. 10/10 would ball again.
