Most everything that HK  sells is    "reversed engineered"  products of  reputable companies.   HK has no  quality control, customer service or warrantees.     They make their money from the shipping charges that they impose.    I've heard far too many complaints from customers and too many  praises from their  paid  shills.   

They pay people to act like  happy customers and praise their products,  so I stay away from them and their junk.
