I have dealt with them and there legit as. Only bummer is the price is to high to make a good profit from, and they only accecpt money through bank transfer. Not sure about the US but in NZ we have to pay a fee to send money overseas to another bank account, and on top of that your money goes through 3rd party banks in Hong Kong and they add there fee aswel. MK have excellent products, but try to use them for personal use. There shipping is good from 3-7 days by ups.
