These port tubes are easy to use. They are made well and feel durable. Once I had the hole cut, these were easy to pop in and secured with a tight fit. I designed my enclosure size to ensure the port length met my needs for frequency response. Overall a good value!

There were no items in the package that were missing or damaged. Good speaker port tubes, has some edge flaking, but easy to smoothen out.
