Yeah, they are great! I usually have like three virtual desktops with two monitors, so it's 6 screens. Switching between them is also much better than it used to be couple of years ago.

Win+ctrl+left/right arrow to switch between desktop. You may need to add a new desktop through the Task View app first though. Works in Win 10 and 11.

Yes it works fine, but I rarely use it though I also use just a single monitor.
