At present, the black Silver fish is obviously more popular in the market, and most of our customers prefer to choose black.  These two Silver fish shell color is not the same, the performance parameters are the same, the choice of color we respect everyone's preferences, everyone is free to choose.

Our mission is  to make clients reduce budget and get good battery.   Adhering to the principle customer first,  always put customer's interests at the first place.
