People know that there will be rearview mirrors on the car, but rearview mirror is not exclusive to cars. It can be used on computers as well. How is your office position? Will you be seen by others from behind often, making you not dare to do what you want? Most companies adopt open space, so most employees have no privacy, a move I greatly disagree! To avoid being peeped unintentionally, there is this computer rearview mirror. You can stick it on the side of the computer monitor with the built-in velcro. It can also be hung on the side of the display for temporary use, and then you can do whatever you want. Computers are very popular now. I imagine this computer rearview mirror should be needed by quite a lot of people.
