Title: This is worth the price only for very specific users.
Content: The real thing you need to knwo is that this is a closed up box, unlike the android add-ons for any other pair of AR glasses, and the XReal software is a not a great schoice right now. It doesn't have the Google Play store. It's a walled garden, and a tiny one at that. An example: it's made to be used only with the XReal glasses, which have a 16:9 aspect ratio, but the UI they provide in the Beam is 9:16 ratio. They put it in portrait mode for a display that only is landscape. Now the rest: I'm a long-time user of head-mounted displays, and have tried several of the current generation of products. In my opinion, the XReal Air 2/Air 2 Pro may be the best set of glasses available at the consumer price point, but this adaptor and the fact it's basically required for some functions you may want, is a problem. Software seems to be XReal's achilles' heel and you will prefer being stabbed in the foot to operating the XReal Beam. You might buy this if you *need* to have the screen in the XReal glasses slowly move to your gaze so you avoid motion sickness, or if you like the idea of sitting in one place and having the screen stay put "in the room" when you move your head. But there are better options for pretty much everything the Beam provides; including those. For the same price as this Beam, you can get a far more powerful and quiet, cool Android phone that supports DP ALT and can turn it's screen off while being used with an external display. Most of the Samsung flagship line does, for instance, a used S10 will cost the same as the Beam and do everything the Beam does* and far, far, far more, while being nice to use, nice to look at, and open to run your own software. None of this can be done by the Beam. *The one thing a DP ALT supporting Android phone won't do is pass through the signal to another device, such as a Nintendo Switch or Playstation, while allowing you to charge, so you can use it indefinitely. For that, you want to buy a simple $25 USB-C/HDMI/charging cable. Or you can find some specialized devices that support the passthrough and power with DP ALT but they are far, far more expensive as of this writing. I've a couple cheaper options for that on order, we'll see. However, it's worth mentioning if you go the Android phone route, you can install e.g. Moonlight, Chiaki, PSPlay, etc and stream games to it at full resolution and framerate, so the passthrough at that point is redundant. The only console that I'm unaware of having this option is the Switch.
