We always can not help but tempt to play with electronic devices such as mobile phones,
 so that our work efficiency is greatly reduced.
So how to help people get rid of the trouble of mobile phone as much as possible?
"C-over" is a smart phone cover that can help you improve your self-control ability 
by opening or lock regularly and reminding you to rest by heating.
Its locks can help you hold  the phone, so that you can watch the video 
or other things horizontally.At the same time, its unique functions also have many ingenious uses.
