Anyone Own A Whoop 4.0 Fitness Device?

Hi,

I've own a Fitbit and Polar fitness tracking device and I am happy overall with them. But I was thinking about upgrading to a Whoop 4.0.

Does anyone own one here? What is your impressions of it? Like it? Hate it? How does it compare to Fitbit and/or Polar?

I understand that it does not track steps. I am not too worried about that.
