If you have tried good quality VR like Oculus, etc., it's better not to buy these glasses, nor any other glasses in the 15 to 20 euro range. However, for someone who is seeing VR for the first time, they are fine. The lenses have poor resolution, 480p and below, while the overall experience is mediocre to bad. If you are a beginner, then you don't need to spend 20 euros or less. Just buy a cardboard for 4 euros to enjoy a VR experience. If you want something good, you need to look at the more expensive options.
