I was thinking about buying a class set of Google cardboard viewers for my class, but I'm not sure what to get. I've used the original Google Cardboard and they seemed fine, but I've never used anything else. They are $15 each on Amazon. Most of the kids have their own Android or iPhones.
There are a ton of alternatives at less than half that price, but not sure if they are worth it.
I've also used these goggles from Merge.
