Terrible experience has left me not trusting this as a viable solution. It was very affordable and getting the serial number was easy and quick. I download OS from CJS CD Keys which added to the easiness of the process. When it did not work and emailed CJDs IT support services the response was quick but utterly useless and insulting. It limited itself to stating that I should download the OS by using the link they provided (which is what I had done in the first place). Needless to say that it didn't work (even if I tried again for good measure). I don't have the time of the energy to be exchanging emails with incompetent IT wannabes. Waste of my money but lesson learned, do not CJS again.
