The website of a specific mouse brand provides complete details about its characteristics. The main features include:

  • Physical characteristics of the mouse (Height, width, length, and net weight)
  • Resolution quality (measured in dpis)
  • The data format of a mouse
  • Microprocessor chip
  • Warranty guaranteed by the company

In case of inability to find the mouse dpi. Search the dpi, by using the Technical Specification feature of the Razer application. It drops the menu bar with the correct optical sensor dots-per-inch of a mouse.
