This is the comment I came here for. Which ones?

I got the RayNeo Air 2 since they had the largest field of view.

Pros:

- Price (~$200 one year ago)

- Display quality/resolution is fine

- Brightness is excellent, can use it in direct sunlight without issue

- Build quality is fine.

- It really is just a plug-and-play USB-C monitor that overlays on whatever you're looking at.

- The focal distance (~4 meters) is really nice since my eyes often get strained when working on my laptop screen

Cons:

- (BIG con) it turns out that the field of view is TOO large - I often can't see the system clock in the corner of my screen or the quickbar in games.

- It just has normal pads like for glasses, and they can get a little sore/leave a red mark since they're heavier than normal glasses

- It's powered by the same USB that delivers the display data, so while it works fine for my macbook, it won't display from my phone. I've seen that there are battery/power converter dongles to add power to the cable but haven't tried one.

So if I did it again I'd just check reviews and get whatever is cheap and well reviewed currently. I was thinking about finding some sort of airplane-friendly keyboard+mouse setup as well but it turns out that just using my laptop keyboard and touchpad works fine.
