The team at tagx are very friendly & helpful! I was initially hesitant about using their services due to my lack of experience with this type of software but they were able to guide me through it all step by step until i had everything set up correctly (and even after that!).
They also have some great tutorials online which helped immensely as well - there's no need to learn how things work when you can just watch someone else do them first :) Great customer support too!! We've been working together since October 2018 so far without any issues or complaints whatsoever. There aren't really anything specific other than maybe having more training materials available would be good? But overall tagging has gone smoothly thusfar.
