I like UNetbootin. It is easy to use and I already created several bootable USB sticks with it. I made working USB sticks with: Win 10 installer, Ubuntu and Elementary OS. First I downloaded the iso files from the official websites with a browser, then I used UNetbootin to make the USB sticks.
I haven't tried this particular version, but I had better success with the Windows version in the past (actually no success at all with the Mac version... It made the key alright but the key was not bootable).
In the end I've used Rufus.exe instead, simple, lightweight and efficient!
