“I bought one of these about a year ago for a rooster, and it worked so great that I bought another one for a new roo a few months ago. I live in town and can have roosters, but, as a courtesy to our neighbors, we didn't want our roosters sounding off all the time. Now people are surprised to know we even have roosters. The first one took a bit of practice getting on just right, but we followed the instructions exactly and eventually figured it out and got the right fit for our roo. Now it's so easy to take off and put back on. Our roosters did freak out about when we first put them on, but within 5 minutes they were fine. Just be sure to check it every few weeks because they do loosen a bit over time, and our roosters like to pick at them sometimes. We have had no problems at all, and the sound difference is tremendous. The roos just sound like they're coughing loud or something. I highly recommend.”
