ultrasonic dog bark

I am about to go crazy from my rude neighbors barking dog. Every morning at 5:00 a.m. she puts it out and it barks non-stop for a half an hour or more. I will buy one of these if they work. I can’t find any independent tests online.
Rescue member, thanks but no thanks. You don’t seem to have a clue. I have called the Sherriff and they say to call Animal Control who says they only come out during business hours 9-5. I have tried to speak to the rude old lady and she cussed me out. I guess her dogs need to bark is more important than my need for rest and peace of mind.
