Please support ALL of your products. The best trackball I have ever used is your trackman wired marble mouse. This finger operated trackball has helped me keep my severe carpal tunnel under control for over 10 years. (Thumb operated trackballs make it worse, and so does using a mouse). It's bad enough that you don't sell it, or any finger operated trackball, anymore, but you could at least still support it with your software. Many of us are still using them (some are even still for sale, but at ridiculous prices since they're rare). That's because we can't find a good replacement. You make it harder to use it than it has to be by not supporting it in Logi options or Logi options +. Please support this product, and even better, sell them again. You're missing out on customers by not offering this product or something of the same design.
