I bought this just because I wanted to experience VR for the first time and I didn't wanted to buy fancy VR costing much more in comparison, I thought it will be a great item for beginners. But I was completely wrong over here, focal length of one lense was not optimum, it gave me double vision. It hurts a lot to the nose as there was no pad or foam material on the supporting edge that rests on the nose. Also keep in mind that you need a mobile with a great screen having dense pixels per inch! With low resolution its useless because you'll be watching RGB pixel squares instead of a nice VR clip. The elastic head band got loose within 2 days of minimal useage. I won't recommend it to anyone.
