Purchased 2025-11 for 37$ with purple track ball. Things I like more on the protoarc than the MX Ergo. Cheaper, Pick a trackball color, 3 device connectivity, USB C, feels pretty close to ergo. I still prefer the palm rubber coating for grip and tactile click on the mx-ergo. I think this mouse beats the m575 easily. For feel MX Ergo still wins becuase of rubber palm grip.

Connections
The connections om this are way better than the ergo. Not only does it connect to 3 devices it has a light up indicator to show what connection you are on when you click the button. MX Ergo needs to copy this.

Notes
- Same tilt bottom with rubber coating as MX Ergo
- I don't think this bottom can be fully seperated which is fine
- USB C Rechargeable Li-Po (900 mAh) battery
- 2 Blue tooth and 1 USB 2.4 GHZ, so 3 devices.
- I got it with Purple track ball.
- I swapped the purple ball in this to the mx ergo.
- The silver MX Ergo ball works fine in this.
- Now I can differentiate my MX Ergos.
