Halo Collar 4 Wireless Dog Fence & GPS Dog Collar, Keep Your Dog Safely Contained Outdoors with App-Controlled Boundaries and Real-Time Tracking, One Size, Graphite

I am going to start this review with a few caviots. First, mine is a Halo 4, the issues with battery charging must have been corrected. If you just got the charging adapter close the magnet makes it pop in place correctly. I tried and was unable to get to not charge like previous reviews. Second the collar works great but one of the hardware pieces (a screw that holds part of the collar together) came loose and fell out. This caused it to fall off my dogs neck. It is a tracking device so I was able to find it real easily. Unfortunately I find it hard to believe that a company selling something as good as this product is in my opinion, and at the price point it sells for, they did not use a thread locking compound line Loctite on the screws. Before the new collar was put on my dog I used a thread locking compound to prevent this from happening. I purchased it from Amazon so returning it was not a problem, and getting the replacement was also easy. My dog is a Rottweiler, if you are unfamiliar with the breed they are extremely stubborn and want to do what they want. This collar with a audible signals only was able to teach her to keep her in my yard. Add far as use, the first collar was less than a month but it kept charge over 24 hours easily. I was always able to track her and tell exactly where she was at. I have a large home and sometimes would wonder where she was. Instead of calling her name which doesn't always work of she was asleep or playing with one of her toys I could open the app and tell what room of the house she was in. She loves the lake and would go swimming or in the woods and be completely out of line of sight. I could send the whistle to the collar and she would turn and come back to the house. As far as in the lake she collar worked great and never noticed a problem from that. I did replace my collar and then found out about a new color. Kind of wish the orange was out before I replaced hers, but I do love the capabilities of this collar. I do recommend it but will say to keep an eye on the Allen screws that holds the collar together. Update 8/25/2025 Nothing in the first review was changed I have added this part. My overall satisfaction of this collar is great and do recommend it. But, I would recommend anyone that purchases a collar to get a pack of metric Allen wrenches. I did return and replace the first collar because the tube nut and bolts came loose and fell out of the collar. The second collar also had the same fault. My dog loves the collar and it fell off of her somewhere outside and she picked it up and carried it back to the house missing the bolt and tube nut. The one side of the collar uses a rivet and the other side uses the tube nut and bolt. I do actually really like the collar, I have had no problems getting it to take a charge, or any other problems. My dog that has this collar and is a Rottweiler. As soon as she gets a fence warning she turns back under all conditions even if chasing a deer. She can be to far from the house for me to hear her barking and I activate the whistle and going home and within 10 to 20 seconds from activating it on my phone I see her on the app coming to the house. My only complaints about the collar are the tube nuts that hold the rubber band for the collar together. As far as customer service I tried contacting them via phone and you have to set an appointment. You can't do a same day, now appointment you have to go at least 1 day in the future. That is not great and I could not communicate with them because of an emergency at my company. So I have never spoken to anyone with the company. My conclusion is the collar is great, I will purchase another if I get another dog, but I will definitely make sure the tube nut and bolt has a thread locking compound applied

Thought I already wrote a review but I guess it never posted or was removed. Anyways dont buy it. Worst product experience of my life. Next to useless if you live anywhere near trees or branches. A single branch is enough to block its signal and the app just tells you "tough luck". But thats after the app takes like 30 seconds to a minute to boot up and then once it finally does, the app then needs to orient itself as to where your dog is... unlike other apps that run in the background... this app appaerntly doesnt and only does once you open it. If your dog is on it way to the fence then it can take up to 2 minutes before you can do anything about it. Half the time turning on and off the fence doesnt work and the app just says "this feature isnt available at this time" or something like that. Why though? Who knows. This results in false corrections which destroys days or weeks of training. It did just that for me. My dog is allowed to leave at night to visit his buddies but the collar corrected him before i could even get the app to open. The app is shockingly bad for a $600 collar with a $10+ required monthly subscription. The fact that this "revolutionary" tech doesn't even have an option to have a normal transmitter that works without a massive 1minute lag is ridiculous. The company is a counterfeit of the SpotOn collar. Whoever copied the idea cut every corner possible to maximize profits. Thats why they sell you very very basic physical hardware to do what free software could do and call them "beacons". These beacons only offer very very basic functions and yet theyre $50 a pop. And ignore the fact that they actually needed to go out of their way to manufacture the beacons separately from the collar... i repeat, the company HALO needed to go out of their way to produce beacons instead of just having their chinese software engineers type up the same code and add it to the collars code. It costs them money inlabor and materials to build the beacons all while they could just add to the software for free and have it do the same thing. Its 2025... the technology exists and its not some elusive niche knowledge. Well they do that because the majority will not even question it and will buy both on impulse. Most people are clueless as to what exactly goes into producing today's electronics... most of the cost is spent on the battery itself.... so a big bulky $600 collar with a battery life of <30hrs means they maybe spent $10-20 on the battery and id guess $100-150 tops was spent on the rest. Also you better believe the company produced a special magnetic charger to special fit onto the collar... so you must buy theirs and cant use anything else out there. Edit again... their special charger sucks too. Mine just stopped working after 2 months. It wont charge no matter what i do to it. Its not dirt or grime which is another thing thatll render it unseless unless you clean it first with a q tip. Its recessed so you cant just wipe it clean with a sleeve or finger... you gotta really get in there. So the collar is now a paperweight until i decide to hand over more money to them and in principle, idk if i want to do that. They're stealing millions while offering the bare minimum for 3-4x the cost of production. They're really good at advertisement though. Their big claims are just lies or at best, misleading truths based on IDEAL conditions like in a wide flat open field next to a cell tower lmao... thats the only setting this collar could appear impressive to the ignorant individual. This collar sucks so hard i cant stress this enough. Its pretty easy to see that even though this company does care about customer satisfaction, its at the bottom of their to do list because they are also milking their customers at the same time. Its a shame my other comment didnt save because theres alot to hate about this collar. Unfortunately I think im stuck with it but maybe Amazon will come through Edit... im stuck with it and its only gotten worse. I probably curse the company verbally on a daily basis... like hardcore cussing to myself using the worst words i know... ive never needed to update a review but this is my 3rd or 4th edit now because it keeps surprising me with its downsides. Makes me want to design one also so I can steal away some of their customer base. I promise I'd do it better than them. All it would take is to hit up a Chinese fab shop and say "make it like this but instead of X, do Y" and youd be all set. If you are envisioning you and your dog hiking, fishing, hunting, camping, or ANYTHING involving tree cover then DO NOT get this collar. It simply doesn't work in the woods. Forget about it. Plain and simple. Doesnt work under branches no matter how thin they are. Basically if my dog lays in the shade, the collar disconnects and the app just tells me his last known location.. but ill end it now because i have much better things to do than talk about Halo... like, well anything really. Very annoyed with this collar. Id love to see this company go out of business even though that would mean my collar is legit useless. Im actually considering paying someone to jailbreak it so I can use it without paying HALO monthly. If I succeed ill be sure to post it here. Sure would be satisfying to know i cut into their profit margins lmao. Im all for it baby. Stay tuned I guess If you have the funds, SpotOn appears to be the only legitimate option. Edit: 2.5 weeks and every time I use the app it makes me want to return it. It does work enough keeping him in the yard but thats mainly because he is a good boy and obeys quickly. But any sub $100 system can do that. But yea more than half the day its spends disconnected. And just now I let my dog outside and realized his fence was turned off (hes allowed to roam a bit at night when theres nobody to bother), so before he has a chance to escape and go visit his buddies, I had to search for my phone, unlock it, load the app which takes like 60 seconds, scroll down to find the fences toggle, and then clicked it from "ignore fences" to dont ignore... and it wont work lol. Message pops up saying its not able to do that right now.... aaaaand my dog escaped and is gone as I type this. Hes not in danger but theres 1 individual that basically hates life and has threatened to hurt my dog so any time I dont KNOW where he is, I cant have peace until I do. So the $600 collar has brought me some peace when it works maybe half the time. But for $600 you gotta at least get the fences right regardless of a medium sized tree that i can see the sun through. I keep ranting because im amazed at the lack of functionality in this $600 item. Edit... this review is scattered all over and hard to follow im sure, because of the frequency I feel the need to update it and warn you not to buy it. The collar's rivets broke and the collar fell off in the woods right as the battery died. Luckily it died right after it fell off so the last known location was close enough for me to find it.... but that was pure luck. Just disassembled everything and added locktight like the company should have but didnt because like i said, they cut ALL the corners producing this thing. Cough up the $999 and get SpotOn. It works for 1. And for 2, no required subscription to use the fences. Garbage.
