I got tired of paying the Logitech premium for the MX Ergo after I broke my second one (both out of warranty, both had the main button switch fail). Ended up with a copycat that works just as well and is 1/3rd the price.
amen to that! I started using a Logitech MX Vertical mouse a few years back to deal with wrist pain. It helped with the pain immensely, but the switches in the mouse failed after ~6 months of use.
I replaced the Logitech mouse with an inexpensive vertical mouse from ProtoArc and haven't looked back.
