Product installed easily and works great. Both my dogs learned the system quickly and were all much happier.
It comes with everything you need! I rescued my dog from the shelter and he has realized he can jump over my fence and has started to escape. I bought him a shock collar and it works great! But that's for only when I'm with him. When I let him outside to play, if I'm in the house he will jump my fence and go. I got this because with his shock collar he responds to the beep and is terrified of the vibration. So with this he won't get near the fence and I can be inside the house and feel at ease knowing when I open the door, he will still be in my yard and not down the road.
This kit comes with everything, and two devices for two dogs. I have trying to find a solution to keep my large dog not to jump our 4 ft tall fence, and this is the most affordable way I found so far.
Great customer service. I accidentally ordered the wrong thing and customer service notified me before it shipped to show me the correct thing to order and refunded me my money for the wrong ideas. Fence was very easy to install and works great.
It might be small. It does a good job. Easy to set up. I up graded to 20 gauge wire.
Fence works great for our 4 stubborn dogs. Easy set up and the collars stay charged for a long time.
So far so good!
Its nice
I highly recommend this system. The collar is actually waterproof and the boundary’s are accurate, unlike the system we bought first
Surprised how well it worked,and for such a good price!.
Product as advertised, showed up on time and works great.
Works exactly like you said, it would so far. I seem to like it a lot. And good quality.
I would give this system 5 stars but I ordered the system with 3 collars and only received one, I contacted seller and they said they are shipping me the other 2 collars. Right now my dogs are sharing. But it's all set up, and it works amazing! I've tried other systems all I have returned since my dogs were being shocked all the time no matter where they were. This one is very accurate, I left it at the preset settings. All my dogs are listening perfectly. No more running away. I highly recommend this product.
I was really surprised at all of the amazing affordable dog fence options available here on Masbrill! This one here works GREAT. My only issue with it is it's a pretty labor intensive ordeal setting it up, and there's a few different parts and pieces to it where if it's not set up EXACTLY right the fence will not work.
It took us a day just to dig the perimeter trench for the wire, then the next day we were definitely out there for almost 3 hours trying to get it to work. I think most important is it DOES WORK- and it works great- it's just alot of work setting up, then alot of trouble shooting and adjusting. We have had ours set up for around 2 months now and it has worked perfectly since the day we turned it on.
My advice for someone setting this up for the first time would to be pick where you want your control panel to be mounted FIRST- for this fence to work 1- it needs to be plugged into an outlet, which might limit people as to where they can place the control panel, then 2- one end of your wire barrier needs to be attached to the east side of the panel, and the opposite end of your wire barrier needs to get attached to the "west" side of the control panel, all in one uninterrupted loop around the area your wanting to fence in. You definitely want to start your set up by picking a good spot for your control panel and work on planning and building your fenced in area from your panel out.
Also, you need to train your dog for a good week or two with this fence before your dog learns WHY the collar is beeping, and how to get it to stop. If you just turn on the fence and let your dog out it's going to be a complete failure and your poor dog won't know why it's being shocked, where the barrier is, or how to get it to stop.
We are very extremely happy with this fence- it works great. It took our dog about 10 days of training. Starting around even day 8 we probably were good. The second this collar beeps my dog immediately stops, turns around, and runs up onto our front porch exactly how we trained him to do. This product comes with everything you need- the collar, the transmitter, the control panel, a huge coil of the wire, bright orange little flag stakes for you to stake out a visible perimeter to help your dog SEE the barrier, and detailed extensive training booklets, set up booklets, and collar booklets. If I missed anything it's not because it didn't come, it's simply because we set it up 2 months ago and I might just be forgetting a few of the things that had come in the box. It comes with absolutely everything you need and it works great IF you properly train your dog how to use it properly. Also, you do not need to bury the wire!! You CAN, but you don't have to!
My pit has blew through so many collars before but not this one! Love it the durability is great. Highly recommend an easy to set up
Shocker work well . He learned quick
I love that you don't have to reset the collar very time the dog goes out!
Our pup is doing great. We tried if for a few weeks before pulling up the flags. It worked like a charm. Best investment ever!
The collar works great, is easy to set up, and takes up very little space, so my dog doesn't feel uncomfortable. Through training, my puppy has become much more sensible and achieved the effect I wanted. This fence works great and is good in all aspects.
If you have an easily trained pet this works well. It is fairly easy to setup and maintain. The collar is adjustable to multiple sized pets, though the device itself can be bulky. I really wouldn’t suggest it for little dogs.
So this is a dog containment device. It allows you to keep your dog inside the area designated without them being able to leave without being shocked. Setting this up, you definitely need to read the directions. Note that your line must come back to the box from where it started. Keeps the dog in the yard and out of the neighbors backyard the reason for buying this is we rent and have a dog and we do not have a fence on the property. Works well looks like it’s build well.
It has great functionality
I made my own little attachment for the lawnmower to plow the wire into the ground. With that tool, it was quick and easy to install. It is working good. We spent a few days with our puppy to figure out what is going on, and it's working great now.
Funcionó lo use en un espacio que quería controlar y funcionó perfecto
This underground fencing pack has easy to navigate directions. I like it better than the GPS invisible fencing because you can specify the line, and you can create the boundaries you want rather than a large general area. I've been working with my dog with a sound training collar to prepare him for this type of fencing. I laid the wire out and tested him and he picked up quickly where he can and can't go. The process of burying the wire is a little daunting but I'm confident that I can get it installed fairly quickly. Because I am going across one side of the house and so have a natural boundary, 650 feet of wire will work fine for me. Check your space in case you need additional footage.
I was having the hardest time keeping my dog in the yard—she’d always run after the neighbors, and it honestly scared me so much! We even tried a remote collar, but without clear boundaries, she just wasn’t getting it. Finally, we gave this electric dog fence a try, and I’m so glad we did! It only took a few low shocks for her to learn the boundaries, and now she stops the moment she hears the warning beep. It was easy to bury, and the setup was super simple and straightforward. It’s been amazing to let her outside while we’re working on things without worrying. She’s so much happier now, and I don’t have to keep her inside all day. This has been a lifesaver for us!
This system is great and very easy to install. Have had the system for over a year now and did recently have an issue with the collar. I called customer service and hands down instantly said they would be shipping a new one. No questions asked! great customer service!!!
I put this in a small area of our front yard so we could let dogs that have had surgery have an area to potty that is separate from the rest of the dogs in the back yard. The beep and static shock warnings work well to keep the dogs within the designated area. The signal level adjustment allows for good control over the range. We use it for a specific application at our dog rescue, but it would work well for the standard pet yard applications. I recommend this unit, but I'll update this after we have used it for a while.
