Works. And assembling fun

I bought this for fun "glasses" and barely had informed me. For the price I saw no great danger.
In the end, even two polished lenses and two magnets were doing (which are mandatory, as I know now). In addition, the NFC sensor, the I but not actively used. Overall, the Spectacles absolutely works as it is supposed to. No reason to complain here. Unfortunately I have found out quickly that my phone is missing a crucial Sensor (Gyroscope), so I can not use most of the functions; which was not mentioned anywhere in the glasses, but in itself is not necessarily their job.
It lacks a guide for setting up. Some may interfere with that, but not me. There was a lot of fun to figure it out themselves.
But what has finally brought me to deduct a star, is that you probably still have to once a cardboard mask off the end with adhesive tape so that the glasses are stable. Maybe I just do not understand how to do it right, but I really do not see any way to stop the assembly without scotch tape. Nowhere is listed (no instructions and so), since I was a little confused.

All in all, I paid with shipping together under 5, so the glasses still remains a clear recommendation, because the fun is certainly time-limited worth the money loose.
