Some of the devices could be bought for less than 10$ can on the net if you search.
A problem with the google cardboard vr headset is that they only work with phones which has a gyroscope. My motorola g play does not have such a device.
Frazew has circumvent the problem using other devices on the cheaper phones:

I am going to buy this cheap vr headset. If you already have some experience with it, this is the place to share.
