I mean if you bought it for 5$, that sound like a bargain to me.
I doubt a cheap headset like that will do gaming VR justice, but I am curious if watching movies on it will work as intended. Because if so, then I would say the product is worth its asking price. You know you use it when you're tired and just wanna sit and watch a movie on a beach or in an empty cinema hall, stuff like that. For five bucks? Having that sort of experience? Definitely worth it.
How did you find one so cheap btw? Did you get it second hand or as part of some bundle deal or something?
I got it of gearbest, and yeah it's pretty cool for movies, but you would need to put something to protect your nose, because it would hurt after 2h.
