It works great! We have used it to setup several VMs at once from our workstation (using an external USB drive).
The only feature that could be improved is if there was some way to change your password without using another program/app since we use windows 10 so everything has been moved into one place now where you need 2 programs just to do something simple like changing passwords. Using qtor to create multiple virtual machines in parallel with ease on my old laptop which I no longer own or can afford new hardware.
