Unfortunately it's near useless since the bulk of the sound is directed towards the back of the bike; and it's the front that would make the most use of it (left turn in front of you, run-over merge, etc). I ride and don't like relying on annoyance for survival: it only makes things worse. Better idea: assume you're invisible and ride with always at least 1 escape route.
