Query: Definitely not "Extra-Loud"

I purchased this bell ringer for our manufacturing floor so that the second shift could hear the phone ringing over the running machines after office hours. This is definitely not an "extra-loud" ringer; just like the other reviews (which I failed to read all!!!) it sounds no different than a standard phone. Totally useless for a manufacturing environment. Don't waste your money. I'm not even bothering to return due to return shipping costs and 20% restocking charge.
