Look, asking if gear is legit is pointless. No one is going to know if your gear is legit. There are 2 ways to find out, use it or test it. Its hard not to be a dick when the question comes up about" Hey I bought this gear but I don't know if its legit".
Here is the best advice that you will ever get. Don't buy gear from anyone if you don't trust the source. If you trust the source then don't question them.
Good Luck
