They are good for some drinks but not great for others in my experience. They do get soggy after a few hours and start to dissolve a bit into the drink so if you use them at home and refill a few times over an evening they aren’t great. They also react with some fizzy drinks and cause them to bubble over.

And it sucked, fov of the augmented area was tiny, the projected images were see-through and you still couldn’t really see the persons eyes because of the tinted glass. Vr headsets with cameras are currently by far the best way to do AR.
