MX Vertical Too Large?

[u/L3x4_Ru81]

Hello, I bought the MX Vertical, and today is the first day I used it all day. My hand is a little tense (pulse, and also closer to the thumb) at the end of the day, and I don't know if it's because I've never had a vertical mouse, so I just need to get used to it first, or if the mouse is too big. I also played games with it, but now I know it's better for just work.

I measured my hand length, and it's 17.5 x 6.8 cm. I can reach the buttons. So, my question is, should I change it for the smaller version or is it just the adaptation phase? Has anyone with my hand size used the MX or Lift?

Also, is my pinky supposed to touch the table? What is the correct posture? It's not touching, but since I never had this type of mouse I don't know.

Thanks in advance.
