I ended up picking up a pair. I thought about buying a pair forever and I didn't want to buy a pair of polarized glasses so when I saw them on the vault I jumped on them. I got them yesterday and never having owned a pair of x-metals, they are absolutely amazing! They do include a coin and I know I could probably pick them up on ebay for elsewhere for cheaper but you always hear about people getting scammed and just decided this was the one item I figured I couldn't afford to get scammed out of. I am already deciding if I should buy a pair of x squared or even a pair of xx. But anyways yes they are awesome!
