mxergo

34mm ball. All of my MX Ergos have USB B connectors. The only way to get a C is to go with S Model but that has silent Clicks which I don't think I will like. For the most part the MX Ergo while expensive is worth it. Feels amazing for a track ball Mouse. I love the rubber coatining under palm. The protoarc has one advantage which is 3 devices. MX Ergos can only do 2 devices.
  1. when the LED is:
  2. Glowing green — Up to 100% battery life
  3. Glowing red — 10% charge remaining
  4. blinking green - charging.
  5. plug the provided Unifying receiver into a USB port, use an existing Unifying receiver, or connect with Bluetooth.
  6. Has 2 Device switch on top.
