Easy to use, effective training aid. All modes work well and stimulation and vibration are adjustable, while the beep mode can be set to different tones. As an experienced dog owner who has trained many dogs in my life, I highly recommend this training collar.
In January my best trained dog that never really even needed a leash and would respond to voice commands or hand signals died. I went to the animal shelter and adopted an 18-month-old highly energetic dog (pointer mix). She was dragging the attendant down the hall when they brought her out for me to meet her. I started my usual training with leash and choke chain and had her walking beside me within the first 2 days. At the time she hadn't learned to respond to her new name (she didn't respond to the name the animal shelter gave her either). and so, I ordered a 20-foot leash and this e-collar.
In my training I decided to use the beep mode strictly for recall. So, as I was training her to "come" I would stand at the end of the long training lead and say, "Duchess, come" and at the same time hit the beep button while pulling her to me with the training lead. In just a short time she had learned the commands both "come" and beep. Now whenever I hit the beep button she immediately comes to me. This works in every situation I have tried it, including in the midst of a bunch of dogs at the dog park, even if she is 100 yards away. This is much better than having to loudly call her name!
The vibration and shock modes have been used for other training reinforcement. Now when we are walking on leash and she needs a correction I will use the vibration. There have been a few situations where I have had to get her attention with the shock mode, but not very often. I walked her through colonial Williamsburg and the downtown area this past week and she did very well staying beside me without pulling. I used the vibrate mode a couple of times and the shock mode once to get her attention when she was distracted by other dogs.
Be sure to use this as a training aid to reinforce commands that you have already taught, or, as explained in my 2nd paragraph above, in conjunction with other commands so the dog will not be confused, but understand what you expect. Above all, in your training remain calm and be consistent with your training and commands.
UPDATE: I had originally posted that the collar stopped working after my dog went swimming in a creek. It would turn on but none of the modes would work. I contacted Jugbow support and got this reply: "I suspect the receiver and transmitter haven't been paired successfully. Here are the pairing steps for the collar: While the receiver is in off mode, long-press the power button for 5 seconds. The indicator light on the receiver will start flashing. Select an appropriate channel on the transmitter, then press any button labeled "Sound", "Vibration", or "Shock". The receiver will beep, indicating a successful pairing." I followed those instructions and the collar is working just as it is supposed to!
Duchess still has a way to go in order to be as well trained as my previous dog. But she's getting there!
