I have a golden retriever that had been previously trained on a different brand of e-collars but lost the remote and this is the one I purchased and I am extremely happy with it. Since it was a new collar it took some getting used to for both dog and people but here are my thoughts after over a month. Overall I would 100% repurchase and if something were to happen to this collar (lost it or something along that line) I would also buy it again, however I do have some things I think would make improvements on it.Firstly we use the sound button as recall, if the button is pressed the dog is to return back to us at our side. I love that there is different sounds/pitches you can use for the dog so finding one he responded to was easy. Depending on the dog you have and their intelligence, I’m sure you could train them to respond differently possibly different sounds since there are so many.The vibration is used to warn him that whatever he is doing we do not agree with and he is to stop, since he has longer hair and even with the longer prongs we really have to work the collar on him back and forth for it to get better contact. Thankfully our dog is well trained enough we don’t really need this one but he does respond to it when necessary.Third is the shock, there are many different levels and is very effective - for sure start off on low levels and build up until it is at a comfortable place for YOUR dog ours is very low about 10.The collars are quite big which is a good thing in terms of fit as if your dog as a larger neck it will fit well but depending on how small the dog you have is you will need to check sizing to ensure it is the proper fit. With this being said I have a hard time having the collar stay in place on him- he is a fluffier dog and the collars are smooth and don’t grip well on his fur even with the proper tightening and ensuring the contact points are proper sometimes the collar does slide down his neck or shift on his neck but again this also could just be my dog being very rough with his collars. So if there was a better option for getting the collar to stay in place better/better grips like silicone on the collar to slip onto it so it does not loosen with time would be a great addition for dogs that play rougher/are harder on their collars.These actual battery lasts very long - we maybe have to charge it every 2 weeks depending on use.The actual collar does have just okay durability- both in terms of the actual shocking/battery system and the actual collar. We have had it for just over a month and the plastic bits are for sure scratched up and have some gouges taken out as this collar is used hiking a lot and the collar is also very well used. My dog tends to go through collars quite fast every few months (2-4 months) he needs a new one he’s very rough with collars, so for durability of the collar part I wish it was a more sturdy material or that I had options to buy just the replacement collars not the whole system as far as I have seen this is not an option. I also wish there was more colors as well for both the collar, mechanism on the collar, and the remote.These don’t seem to be reflective- which is something that I think would be a great addition to these collars. Same with even a button for a light on the collar to not only be able to see where the dog is at night situations but also a bonus if there was an option to turn a light on the collar and keep the light on, again for safety at night.We are also looking into getting him a tracking collar and having to put both a tracking collar and his e-collar collar and his regular collar (a lot I know but we do this for dog safety) is a lot - I wish this collar did both the e-collar capability and the tracking capability.In terms of the actual hand remote it is very nice very durable has been dropped and have had no issues with it. Very user friendly and little to no weight to it. My only addition is I wish it had a flashlight on it to use in night hikes/walks so I did not need to carry more on me and I wish it had a clip as well rather than the short lanyard so I could keep it around my neck or attach it to my clothing.Just as a summary I am extremely happy with this collar and has been easy to use just wish there were some small additions to it and it would be even more worth it.

always pleased with this company, quality dog collars, leashes etc, Fast shipping, I highly recommend

If you're looking for a reliable and effective dog training tool, look no further! The build quality is top-notch, the battery lasts for ages (over a week!), and the remote has an impressive range of at least 300 feet. Most importantly, this product has made a noticeable difference in my dog's listening skills, simplifying the entire training process. I highly recommend it to any dog owner who wants a more obedient companion.

Tienes que saber utilizarlo, no esperes que sea mágico y solucione las malas conductas de tu perro etc, recomiendo consultar un profesional o que investigues sobre el tema. pd: tengo un malinois

I got the dual package so i had one for each of my dogs. At first, i found it very effective. Then my females completely stopped working and charging. NOW, the other one fried my male gsd on a level 1 stim. We are in IPO/shutzhund training and it completely messed up his heel and shut him down. I tried it on myself and now i get it. a LEVEL 1 fried him? Terrible. Only had it a few months......

Holds it charge for a good few days with persistent use, unfortunately my dog got used to it really fast and stopped responding to it, would be better for a med- smaller sized dogs, I got it for my German shepherd and his neck and fur is way to thick for the collar to be used to its full extent for training, not a waste of money tho!
