"This is really a great product. Got it at a good price here while on sale, too. It was a bit time consuming to get installed (I had about 600+ feet to install). After I got a system going it went pretty fast though. Overall I got it done in a few days doing about 2 or 3 hours a day. I'd say, honestly about 10 hours of labor. I did end up buying 500ft of a heavier gauge wire from a home supply store for 20 bucks. It's a little more durable which made installation a bit more worry-free. Getting it running was a piece of cake. Plug it in and it's good to go! As for training, wow! The video and print training guides are very good. I will say though, my very excitable Lab/Shepard mix learned very quickly. I admit that I had my doubts about this type of restraint. But I tried it out on myself first and although it feels weird, there was no pain. Then my dog experienced it and it only took a few times (like 2 or 3) along with me "explaining" the flags and boundaries to him and he got it! He did great right from the first few days. We still train, but I feel confident after just a week. I'd recommend it to anyone. Take your time and install it right and also take your time to properly train your dog. The result will be more freedom for your dog and for you."
