The ability to install Add-on is probably the most fascinating feature of KODI by which customer can install numerous adds-on that customize its interface. The open source feature makes it available for users to build their own favorite adds-on. Accordingly, there exist so many unauthorized adds-on by which users can stream pirated contents.
As KODI is a free app, you can install it on variety of media boxes such as Amazon Fire TV, Raspberry Pi, PC and etc. However, the main drawback of KODI is that streaming KODI content is quite tough as well as its interface is not user friendly in comparison to other apps such as Plex.
