"Easy to use"
Easy to use if one knows how to run an executable file from the download location. No program install required.
No cons for infrequent use
MP5 is new to me. I can use a command line, but wanted something simple to run on an .iso file I downloaded to a desktop folder. Also needed a quick compare with a text file containing the mp5 checksum sent from the vendor. Worked great. If I use this often will look elsewhere for more advanced capabilities.
