Amazing service from the Fly Online Tools group. I have been using the Quantum MX package for years. It is easy to operate, everything is stored in the cloud so it's easier to have everything on any computer. Most amazingly, every time I have called for help, or to fix a bug in the system the problem is resolved in minutes, not days or even hours. I cannot remember any company that have resolved issues consistently just moments after discussing them. Kevin Kane, Director of Maintenance
