I like how they have an easy way for you as their customer / user which is very helpful especially when i am new at this business! It's also good because it helps me improve my knowledge in terms what kind products would be suitable if ever we get some problems later down our line! There isn't really anything bad but maybe more training material could help out there since sometimes its hard getting used too fast without enough practice before hand (i'm still learning).
The most useful part about them was probably being able learn something from other people who already working within those area so far nothing yet :D.
