I like how easy it is to set up for multiple users; also love that you can use this app with other programs as well (such as Google Classroom).
Also have used before but was not able to integrate into more than 1 program due to lack of support from their side or my own fault! So glad we found another one so far better. If anyone wants something they can easily share across platforms without having issues then definitely give them try!! We are integrating all our classes together now through google class room which has made life much easier especially when students need help outside school hours etc..
