There's also tons of reviews on YouTube, but if you have any specific questions about them, I'm happy to answer them.
These are only the glasses, no R1 control ring. They function pretty much as advertised. Super cool tech, I just didn't end up using them enough to justify keeping them. They're practically brand new, I've worn them for five or six weeks, but no wear or tear, still in mint condition. Comes with the charger case, of course. Let me know if you have any questions or if you just wanna try them out and see if they're what you're looking for.
