I have the XREAL One Pro. It is polarized which makes it always dimmer, especially indoors, and they sort of PWM from the polarized state to a 99% black out with a button interface. When it's really bright outside and you have the display on, you can see barely where your next step is and not much else.

Their AURAs are probably the same in this specific capability, it looks like the same thing I have in my hands, apart from the extra cameras and a different set of buttons.

The projection lenses look the same too, which means there's no periphery at all. That makes the sort of "screens hovering around you" in the advertising not all that representative of the experience. You see what's in front of you and might barely contain the one screen that you're looking at.
