This kit comes with everything I needed besides a way to dig the hole for the cable. I have experience with these fences so that’s helpful. The first time I ever had to install an underground wire and set up I did find a very nice selection of DIY videos online. I will also say that after pricing out how much a professional was going to charge, I decided I had to learn how to do it myself. I have never regretted it and it’s not nearly as intimidating as it can look at first. At least that’s how I felt the first time.I like that this set comes with a surge protector. Although a surge protector is optional, I think it’s important to protect a unit that’s so important to my dogs and my peace of mind. I have my surge protector and transmitter plugged into a garage outlet.My dogs were used to the training from before so I just had to put up flags and I verbally reminded them that there was electric fence in this new location. I am sure they didn’t understand but it felt important to keep them in the loop. The flags are very durable and last a long time as long as you don’t hit them with the mower (which I accidentally did a few times).The collars are very lightweight. The weave is tight and the material is thick enough that it doesn’t wear quickly. Each module has two electrical tips and there are choices of long and short ones. I have a beagle and a Labrador and used the short for both of my girls. They were both very quick learners and only the beagle will push the limits to make sure her battery is still working. Smart little girl. This is also where the test light tool is invaluable! Otherwise you have to listen and/or test the collar yourself which I am sure the company doesn’t recommend. Although full disclosure, when I set my collars, I find it important for me to understand what it feels like. If I am subjecting my dog to something then I want to know exactly what I am asking of them and if it’s reasonable. It’s certainly a deterrent but if other dogs are like mine, the training was enough for them to be satisfied to not push it to the limits again. I do like that it warns the dogs before emitting any sort of correction. Also what I like about the collars is that they are waterproof. The dogs can wear them while playing in their doggie pools and the sprinkler with no negative consequences to pup or the unit.I will say that whenever I have had questions I have found customer service to be very friendly. They are available to answer even the most simple or complicated questions. This is a product that has been well thought out and delivers the service it sells. The comfort in knowing my girls are ‘free’ to roam safely is completely worth the time of training and money for the system.
