We love that we can access our calendar remotely via computer/phone which is great when in meetings or traveling! It's easy enough so new hires don't have an issue navigating it at first but also intuitive once you get used too (at least I think).
The only thing about centrello was there were some glitches where if someone clicked into my area of responsibility they could see what hours i worked during those days even though everyone else couldn’t unless assigned as their supervisor - this has been resolved now thankfully!! But overall its pretty good- still not perfect by any means since everything isn;'e always 100% accurate due ti human error etc.- sometimes things will go missing between workflows like paychecks going out without being approved properly ect.. So be sure yo check up front before accepting anything because nothing seems right until after payroll gets done anyways haha.
