Jugbow Dog shock collar

I have only opened and charged the product so far. The product was packaged well and materials are high quality. Both the collar and charger have a light to indicate they are charging and the process is quick. After charging and during use, make sure there is a flashing green light. Now I need to learn about usage.... I may come back later and post further details after I use the collar on my dog. UPDATE 10/23/24: This is an incredible product! It is very versatile as it has several settings and intensity levels. I have a 1.5 year old Yellow Labrador Retriever. I used the vibration setting on the remote and put the intensity level at "10" to correct several behavioral issues with my dog. This setting only gave my dog a vibration but it stopped my dog in his tracks immediately. His initial response was to look behind himself as he thought he was being attacked by something. He soon realized that when he disobeyed commands or came near particular plants, places or things he received a buzz. It only took one or two instances of buzzing to get him to stop a bad behavior. This product is nothing less than miraculous. I only regret not purchasing this product sooner. When my dog was a puppy, he created lots of frustration acting out his will. My dog had the following behavioral issues: 1) not responsive (ignoring) commands to come into the house when outside, 2) urinating on sensitive rose and other flowering bushes and burning them, 3) twisting his head to the ground and flopping over so that it was impossible to take put on/take off his tie-out lead from collar, 4) grabbing soil from my potted plants and eating it (he kept getting parasites from this behavior), and 5) grabbing paper, plastic of all sorts, and other objects/materials off the floor or out of garbages and eating it and making messes. To begin his behavioral training, I simply carried the remote with me any time I walked around the house or took my dog outside to poddy. When I witnessed a bad behavior, I pushed the upper most left vibrate button and gave him a 'buzz." When my dog received a buzz he became highly irritated and a bit spooked by the buzz and instantly stopped the bad behavioral and vacated the area. Sometimes my dog goes back to a bad behavior a second time within minutes, however, when he receives a second 'buzz" he does not return a third time. I previously mentioned the 5 top behavioral issues that my dog had and one was urinating on rose and other delicate flowering plants... I taught him over the course of one day that he couldn't urinate on certain plants without getting a "buzz." Since this time he has never urinated on these bushes, but does so on other bushes (oleanders) that are tougher than nails. So, you can actually train your dog to poddy in certain parts of your yard and stay away from others (like delicate plants, a newly planted tree, or real or synthetic grass as examples). Every once in awhile my dog may want to exercise his will and go back to a bad behavior like twisting his head to the ground while attaching the tie-out cable/lead to his collar. (Not sure why this has been such a challenge to correct!) In this instances, I start to carry around the remote control for a day or two and anytime he misbehaves, I correct him with a "buzz." And wah lah he's broken of this bad behavior for another spell of time. In earlier times, these types of collars were called "shock collars" and actually inflicted a bit of pain. However, with this collar there are so many different setting including noises and vibrations that are very humane and do not harm dogs but only serve to startle and scare. My dog has never cried or whimpered during/after a buzz. This setting only startles him. Before you use a setting, I suggest using the setting on yourself against a clothed leg. If the setting hurts you-don't use it on your dog. One last comment... Both the remote and collar have a flashing green light when working. When either doesn't have the flashing green light it is out of charge or not switched "on." The remote and collar run out of charge around the same time. When one device runs out of charge the other usually runs out a day or two later so charge them both around the same time so that they are on the same charging cycle. I have tried to use the collar several times when it was out of charge and wondered why it didn't work. Haha... I highly recommend this product for its price competitiveness, quality, safety and overall effectiveness. This definitely was a game-changer for me and my dog and has eliminated many frustrating reoccurring acts of disobedience in a humane way. This product has dramatically improved the relationship between me and my dog by increasing our happy moments and eliminating a lot of frustration. Happy dog parenting! :)
