I like how easy it is to use with my mobile device as well which makes life much easier when traveling! Can't think of any downsides at all since this program was very useful for me while working abroad or away from home (i needed something that could be easily run off an app).
This software allows you to remotely control your computer via smartphone/tablet so if someone tries they can see what you are doing without getting access themselves. It also lets people know who else might have gained remote user accounts through another means such as social media hacking etc..
