Great product! Almost too quiet!
Bought a full set of heads and I am really impressed. They are super quiet. So quiet I got some painters tape and put strips on them to raise the volume and give some more tone after I saw someone do it on youtube. That works fine and it raised the volume to a comfortable level so I could jam with a buddy playing acoustic guitar. As a drummer with tinnitus its great to have a kit (with the Zildjan low volume cymbals) that I can just sit down at and play without having to worry about my ears.
