Contour or Extreme

Hi, is there any difference between flash drives with sign on the black side Extreme and Contour? I’ve got HD USB SanDisk Cruzer Contour U3 - 32 GB with sign Extreme and the all pictures are with sign Contour. Isn’t it another product type or type for Europe for instance. Thanks. Sorry for my English.

The Cruzer contour was remaned the Extreme Contour. Same product.
