Barking when left alone

My first problem with Corbin curred the first day I left him alone at home. From the minute we left he would start barking for hours driving our neighbors crazy. One day, I found the magic and painless cure: Lentek's Bark Free Dog Training device

• Problem: Continuous , non stop barking
  
  
• Bad Solutions: Shocking Collars. There is a huge market for shocking dog collars. These device sense the vibrations on the dog's throat, and eventually discharge a static current. I tried it on myself (180 lbs guy) and really felt the shock. Nevertheless I dared to try it once on my dog when I left him at the car alone for a few minutes. When I returned, he was in shock, super scared, and yes not barking.
  Although this is a solution, I found it too extreme

• How does it work ?
  This box has a microphone that senses dog barking, and emits a "corrective tone" when your dog goes out of control. Simple, but works like a charm for my little poodle.
  
  This box has two modes:
  - Audible Frequency: Everyone can hear it
  - Non-Audible: Only the dog will hear it
  
  You can also set it to:
  - Highly Sensible: Reacts at the smallest sign of barking
  - Low Sensitively: Only when the dog repeatedly barks
  
  
• My Advice:
  - Set it to Audible Frequency and Low Sensitivity, so that you remember that is one when you get back home. Otherwise your pooch will get confused, when you make a high pitch noise and the box makes the correctable noise.
  - Your vacuum cleaner can trigger it, so be careful, specially in Non-Audible mode. However outside noise like car breaks, trash trucks, etc, will not trigger it.
  - This is a correction device. After a while, my dog didn't need it anymore, so I turned it off. I now only use it for special occasions, when I break the daily routine and situations that may confuse him
  
  
• Gadget Usability Rating:
  My neighbors and I give it a 10/10.
