I have been using it for over 4 years.
It is the real tool to save backup and active work and professional materials.
Each year new tools and resources are released.
Always up to date.
Easy to use.
Handy for all file manipulation and management needs.
And most importantly, I feel safe using it.
The price is not the cheapest.
A plan for longer users could be granted, but it's still worth the service.
