I really want to buy this lens but I'm scared of getting it and realizing it's not legit. I've had issues before of buying apple earphones on ebay and then getting them and they don't sound nearly as good as the ones from the store. so I just wanna be careful especially with an expensive item like this.
Can anyone help me out?
