USB extenders offer great flexibility to you and your devices. Sometimes the factory length of a USB device isnt enough, so an extender can offer that extension you may need. Typical extension distances can vary, starting from 5m up to 100m. They also typically feature 1-4 ports for convenience. Practical uses may include having to reach a projector from your PC/Laptop or any other long distance device that wouldnt be practical to home your computer near it.
