Trash Without is a program designed for Mac users who wish to immediately delete sensitive files without sending them to Trash. The application lives on your Menu Bar from where you can configure its settings according to your needs and delete files from your Mac or Trash app with just one click.
This utility is compatible with many OS X versions (from Snow Leopard to El Capitan) and uses a small amount of CPU resources while running on your Menu Bar. After you choose the files you need to remove from your Mac or Trash app, the program immediately gets the job done.
You can also drag-and-drop the app's icon to Finder's toolbar. This way, you can delete files from Finder app by dragging them over Trash Without's icon.
A thing you might not like is the fact that it lacks a built-in help guide. Even though it features a Help button on its main menu and Preferences window, if you click it the app redirects you to the homepage of the developer and not a tutorial page.
Other than that, not much more can be said about this program. It simply does what's being stated on the homepage of the developer. So, I'd say it's worth acquiring this product if you require a quicker way to permanently remove files from your computer.
