Please find below pros and cons listing regarding the product you found
and asked to comment.

I would assume that the product made by a fellow-countryman of mine
might suit your purposes.

Possible minus points are the lack of erasure of deleted e-mail and that
Eraser apparently does not remove information from sensitive areas such
as the Windows Recycle Bin or swap/paging file.

+ Erase, wipe & overwrite with U.S. DoD methods (5220.22)
+ Advanced methods to stop practical recovery of even the most
sophisticated hardware recovery tools
+ Customizable data erasure overwrite settings
+ Create your own data erasure wipe methods
+ Erase & wipe data on both "normal" and compressed drives
+ Erases, deletes & wipes existing files beyond practical recovery
+ Erase & wipe entire folders with all their subfolders and files
+ Erases & wipes the slack portion of deleted files
+ Ensures no recovery of deleted data or parts thereof (file slack) from
previously deleted files

Cons (does NOT include the following):

- ISAAC Random Generating Algorithm
- Protects your Internet privacy- erases browsing trails you leave
behind: history, cookies, texts, pictures, etc.
- Can help ensure that no one will recover your deleted e-mail
- Removes information from sensitive areas such as the Windows Recycle
Bin or swap/paging file
