The format of that rule looks fine to me.  You might look in
the logs (/var/log/secure if you've got syslog enabled, else
use the journalctl command).

It may be that you're hitting another rule which supercedes
the one you've got there (for example, if there's a rule
matching a group you're in).  Using `sudo -U mike -ll` might
be helpful.

+1 for Todd's comments, I have added a couple of commands and I was able to access those commands without being prompt for the sudo passwod.
