This is an odd product with a really strong theoretical concept

I suspect that this product would be even more effective on less expensive guitars

This is an amazing product

I typically don't leave reviews, but this is a great product

Great product

So nice when a product meets and even exceeds expectations

The product is flexible enough that I was able to just fold it in half and slide it under the strings and into the body

Overall, I really like the product

But this product was a waste to me.

I would most definitely recommend this product!

This is an amazing product

Innovative little product, and certainly made some difference in sound and resonance

The product is inexpensive enough to give it a try on speculation

If product wasn't damaged at the time of arrival I would've tried to get this in but didn't want to damage my guitar or handle a damaged product.

I highly recommend this product to any serious guitar player.

Sorry, usually Planet Waves makes great products.

I can acknowledge that Planet Waves makes excellent products, but in this opportunity they failed

I really wanted to like this product.

I wanted to try this in my natural Martin with dual P/U, but the electronics extended all the way to the rim, which made putting in the O-port impossible without cutting it.

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

The O Port cracked and broke with my first attempt at installation.

The O-Port enhanced fingerstyle play, but it also added clarity to gently-rolled chords

The O-port works

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
