The iMice x7 can have many configurations changed for the 7 buttons also DPI adjustments and macros using the iMice x7 software. The mouse that you have may have been name many different names depending on the distributor, but visually and technically they are the same device.
Extra note, these drivers don't work on all X7 mice, sadly there are a bunch of variations that use different device ID's which means the software drivers can find the mouse (fig.1).
