Received collar first week of July 2012. The receiver batteries wore out in mid August, and transmitter batteries by the end of August. Otherwise the collar works great. READ the instructions to set it! It doesn't get 5 stars because of the batteries.
Using this with my 1 1/2 year old lab, spaniel mix. The vibration setting is just enough to distract him when he starts to get into trouble and then he listens to commands as desired. Not sure if I will ever use the sound setting but I suppose it could work for some dogs. Had it for 3 days so far and it's working great.
Many dogs simply do not respond to traditional training methods which is why thousands of owners and professional trainers have used training collars to assist them in their training programs. Training collars can help you achieve a well trained and contented dog within days. This compact, easy to operate system will control bad behavior and dogs who run off when taken outdoors for exercise.
