Installation of O-Port when strings are attached was easy.

After the video I tried by hand simply to bend the O-Port to see how easy it would be to reverse the process and it didn't seem difficult to uninstall, just not as easy as the initial installation.

I recommend that you also watch the video for the easy installation technique

First installation is easy - I didn't even loosen the strings

Very important to ACCURATELY measure your sound hole diameter for the right O-Port (small or large) and "be

I also found that there seemed to be less vibration where the back of the guitar would make contact with me (though that seems to be changing the more I play the guitar after installing the port).Is the O-Port worth buying

I got it in just fine, but then had to use a thin tool (smooth end of nail clipper lever) to coax the part of the o-port that lacks a rim out of the guitar to fit along the inner edge of the top of the sound hole.

I've read from other reviewers that the O-Port helps to suppress feedback, which would be a point in its favour

The O-Port fits snugly - but not overly tight - which is good when the time comes to remove it, as well as reassuring it's probably not influencing top plate stresses and vibrations
