It's easy to install with all that is needed being included in the box. I really like how simple it is for customers to navigate my menus which allows me to focus more on other duties or tasks while also meeting their needs as well. Nothing so far! We are using this device at various locations throughout our campus. At first we were having trouble getting the sound right until an employee suggested changing out some components such as speakers, volume level controls, etc. This has made a big difference especially when displaying presentations from one location to another where there will be less than desirable conditions.
