Review on 📦 I Am Cardboard Five-Pack VR Box Set: The Ultimate Bulk Virtual Reality Viewer for iPhone and Android - Google Cardboard v2 Headset Inspired by Juan Lockwood

No, they don't have a button like the official Google Cardboard. There are holes at the bottom to put your finger through. I actually like it better. The button may stop working, but the hole does not. It is also compatible with both right-handed and left-handed users. They are cardboard, like the official Google. They are not very durable but functional enough for everyday home use. That's a really good deal. I paid $25 which is $5 per viewer which is great value.
