Very good wire
I installed this wire two years ago to keep my golden doodle out of the garden and pond area, which are on opposite ends of the yard. I wanted for her to be able to run in between the two areas. This wire is easily installed, and when it is twisted together it cancels out the signal so that one boxed in area on one end of the yard can be connected to another area on the other end of the yard, while allowing the dog to run without getting a shock. All of this wiring then runs into one control box for power. My dog has learned very quickly to stay out of those two areas. The collar shock is adjustable depending on the size or tolerance of your dog. This is really good wire and is easy to run.

Effective and humane - and I have a very smart cat
I'm sitting here at dusk with doggie door and back slider open for fresh air. I'm totally relaxed because the PSBW installed Sunday is working perfectly and my cat is safe. Testi is a 20# castrated male measuring about 15 - 18 inches long. He's smart, cunning stubborn and adventurous. I've been tortured for 3 years with the fear of his being killed by coyotes and our 3 dogs have been equally tortured by being locked in and not being able to use their doggie doors whenever they need to (fully double fenced, and dogs can't jump 4ft & 6ft fences like cats do). All it took was 2 training sessions, once on Sunday afternoon for about 1 hr (with harness & leash), one today for about 10 minutes with just leash and collar. What a smart cat and what a great system. He found the boundaries on leash, then tested them off leash. I was unable to video bc my phone battery died just as I started my observation.

Awesome!
We had an invisible fence at our other home and I was so happy we got this for our current home. The dogs are happy to have freedom and not getting tangled in everything. Husband and I easily installed the fence. We got 2 collars. All works as expected and it's so nice to work outside and know the dogs will stay in the yard.

Great fence
For 55 dollars it's not a bad deal. But, you will need to order the wire also avail at amazon. The wire they give is crap. But ya get 2 collars and he box, which I think is still a good deal. I have a acre and 1/2 but didn't do the whole yard, prob 3/4, I have to get 2 rolls of the 500ft wire for 20.00 each, so now it's up to 100 bucks which I still think it's cheap enough. It's a huge pain I the butt to bury the wire, we had to rent a trench digger for another 80 bucks at Home Depot and my husband had to install it since it weighed a ton. So I was I to it for at total of about 200.00. Oh ya and just buy a battery cuz he one they gave me lasted 1 day. So it took all weekend to install and my jack russell got zapped once and that's all it took, the fence works great, but he is afraid to go outside now, I'm hoping he gets used to it, everyone told me a jack russell would run right through it, not mine. Still I think it was a good deal just a huge pain to install. A lot of people said the directions were messed up, they are but you can figure it out. All in all I'm happy with it. They tell you now to train your dog. Just make sure you have lots of time to install it.

So much better quality than the wire that came with the PetSafe Boundary Fence
The original wire was so thin and flimsy, that it took me a lot longer than expected to get the boundary laid and buried. Working with the original delicate wire took so long that my dog got ahold of the wire and shredded it before I could get it finished. So, I got to order this replacement wire and I am so glad I got this durable wire. It did not take nearly as long to work with and is not dainty like the wire that came with my PetSafe Boundary Fence. I highly recommend to just replace the wire and get this for your install. You'll get it done so much quicker without all the hassle of easily snagged and broken lines.

Works Great
I used this wire to put in a fence around roughly 1 acre for my dog to be able to run outside without going on the road. Has been in the ground for a few months now and I have not run into any issues so far. Works as it should. Would recommend to anyone who needs a little extra wire
