The app is very easy to use, it makes it really simple to get into the technical details of how a device works or what's going wrong with an application when things don't work as expected. It also has some great tutorials that walk you through features like Xcode integration which can be difficult but not impossible if you're willing to put some time into reading about them. At this point I'm unable to find anything negative about this product. There are plenty of resources available online so there isn't much left to learn or discover unless one decides to dig deeper than the surface level documentation. As far as being able to solve issues quickly we've found ourselves using this feature more often than our other tools because of its ease of use and ability to connect us directly to Apple support reps who will help diagnose problems faster than ever before.
