Such a great price and I was able to get it installed in 5 hours. We just used an edger tool but if you have several acres, it may be worth renting a cable installer tool. We have around 1/3 of an acre and followed the hourglass layout which allows the dog to be in the front or back yard, but requires them to go through the home when going from the front to back yard.Be careful when you take the cap off the collar to change the static level. My first time taking the cap off to change the static level, I used the tool and still stripped the cap. From that point on I had trouble getting the cap off and had to use pliers to get it off. I contacted and they were able to send me a replacement cap. A+ Customer service. I also purchased more replacement parts for the collar on here for only $6.99 for my own ease of mind. My recommendation is to buy a thicker wire than what it comes with.Training the dog was super easy. My dog got to the point of staying inside the perimeter with the tone only. I was nervous to use the static correction during Day 2, but quickly realized it was necessary as she ran through the fence to the neighbor on level 2. She didn’t even feel it on this level. I have a 12lb dog and level 3 correction level ended up working good for her. After a few days of walking the perimeter and being shocked a few times after we baited her with toys, she’s a little shy about being in the yard now but refuses to cross the fence. We can work on the shyness and can be expected. This is so worth your $$ and the is reliable and ready to help with any issues you may have.
