If you're looking to dabble in VR using the smartphone you've already paid for, instead of spending over a $1250 on an Oculus Rift or HTC Vive setup, Google Cardboard is a great affordable alternative. But why spend $20 on some folded cardboard when for $50 you can get Mattel's upgraded View-Master VR that's more comfortable, more secure, and is compatible with a wider range of devices.
