At that time, in the choice of the product of my own but is tangled in the end choose which brand products, fortunately my friend gave me advice let me choose this brand of adapter, I have to say this is the friend’s taste so good, if not others recommend myself how would know the brand of adapter it is so good, but the price is also within the scope of my own thought, also used a lot of the same type of products before me, but he never gave me the impression of a product which is so good, we will only look for the brand adapter, other brand products never think, good stuff is to always use.
