Logitech MX Master 4 hiiri, vaaleanharmaa

Didn't know Action Ring feature is so amazing, that really supercharged my productivity.

With one click, I can do time logging, search suggestion in chatgpt, create Jira ticket and much more.

Have not been so excited about a mouse like this for long.

Other interesting observations compared with MX Master 3S

• More quiet clicks and scrolling wheel
• No more rubber shell, way more comfortable now.
• One more button on the side
• Haptic feedback is strong
• Same polling rate
  
  

If you are looking for just a ergo mouse, go for MX Master 3S. If you look for mouse that supercharge your productivity, this MX Master 4 is huge upgrade, it already saved me a ton of time during my work day.
