A software is required to enable the full functionality of the mouse. The user was greeted by a login screen which couldn't be bypassed, and even worse, the account creation didn't work at the time. It turned out that the Razor activation server was down. As result, channelx99 was left out in the cold, and he wraps up 'Nowhere on the box does it say anything about needing an internet connection to "activate" a mouse. If the servers go down in the future, anyone who buys this mouse is out of luck.'
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
