Many of Chinese suppliers ask clients for retail or gift,then they will decide to what kinds of chip quality used for,usually terminal clients complained to that becasue poor quality ,like lost data file,crushed file or upgraded and so on.the user are very angry with that if their userful data file get empty.

We are a trust factory from China,we never cheat any clients.this is our basic reputation
