Our company has been using the brand adapter, the brand began to use the adapter because of a friend’s recommendation, I in addition I was also want to change a brand to try, so after my friend recommended adapter I immediately decided to buy, but the adapter the quality of my own than expected a lot of good, I also used a lot of the same type of products, but because the quality is always not very good I have no choice to buy again, but this is not the same as adapter is the first impression to me but it is particularly good. Our company will only recognize the brand adapter.
