I was alarmed by your comment and had to go to the website to confirm it is still for sale.
Also: I switched to this because of wrist issues. I really think having this large marble trackball at your fingertips could be helpful to a lot of people. Give it a try! It's cheap.
I think it's been at least 10 years for me.
One nice side effect of the design is that you can switch hands if/when your wrist gets tired (I write with my left hand and throw with my right hand, so ambidextrous trackballs work very well for me).
I've had other trackballs along the way, but this one suits me best, all the more so given that it's small and lightweight (on the road most of the year).

You can also add the lack of reliability to the drawbacks (more hardware, more software involved).
I am fond of thumb trackballs, and the M570 I was forced to buy did not last very long ('forced' because I did not want wireless). It stopped working after a while, without any visible sign of damage on any component.
Whereas my much older Trackman Wheel (the same as M570, but wired) is still my daily driver after more than 10 years.
Not a deal-breaker, but if your pointer acts erratically, clean out the enclave first!
Their recent release is wireless, BUT it comes with a rechargeable battery via USB. And they also provide you with a USB receiver. Furthermore, the scrollwheel is really good quality unlike their previous offerings. I like it.

Googling “wired trackball” finds quite a few available from a wide variety of sellers and manufacturers, and Logitech clearly thinks they still have them.

There's a forthcoming linux kernel fix to get the right button to work on the EX-G models.
Unless you are using it on your leg, on a sofa. Trackballs are second-to-none for home cinemas. Regardless, most are semi-wireless (such as the M Ergo) - just keep it plugged in.
