I like that it works with all my devices, even when they are not connected to the internet (like in airplane mode). Sometimes it takes some time for the app to load but once loaded you can use it without any problem. The interface is quite simple so anyone who has basic knowledge about computers will be able to figure out how to work with this software. There isn't really anything bad about this program. You should give it a try if your looking for something easy to use. This is great because I don't have to worry about having access to WiFi or data plans while traveling.
