I am using SHAREit from 3 years . It is very good app for sharing files , video , images etc. It is also very easy to use and for transffering one of the open hotspot and one of the wifi. The one who sending files he opens wifi and the other one is reciving , he opens hotspot when both are connected to each other then the transffering of file will be started this the concept behind the SHAREit. The layout and designs are very good of shareit than others. The features of shareit is also that you can chat on shareit with transffering files in new update. The speed of transffering file 5 mb/s . It is very useful for us and it is very fast for file transffering in comparison to others
