I had very bad experience with Winball. They couldn't repair my Nikon Camera lens well. And they don't have the instruments/equipment for the repair. When I picked my Camera up and found out the camera couldn't work well, I asked the questions, the owner Raymond couldn't answered it, then his wife said they would call 911. My God! Their small shop/work place is inside of the house beside the garage. The garage door always is closed.
