Installation: It takes a little time to get it in the ground, but it is worth it. To put it into perspective, I have just under an acre and it took me and a friend under 5 hours with nothing but a narrow shovel and a large paint stirring stick to push it in the ground. Spring time when the ground is still wet was the perfect time.Does it work: I have a 60 lbs. German Shephard/Blue Heeler mix puppy that is extremely active and very hard headed. It took a few weeks to train him properly and still had to use the highest setting for a while, but he stays in the yard now. I watched him chase a cat and go from a full sprint to a sliding stop when he got close to the boundary line. The only problem I run into is now that he is trained, it is difficult to get him out of the yard. I have to pick him up and carry him over the boundary line while he is squirming because he is afraid of getting shocked.It is great to be able to give him the freedom of roaming his full yard without having to worry about him chasing the neighborhood kids down the street or wondering off....

Works as advertised. The static/shock setting is very intense, so please start at one and work up from there only if required.

It’s a great dog training collar. It arrived on time.

I would recommend this training collar to anyone who want’s to shorten the training time for a dog with behavior issues.

The dog training collar is well made as is the transmitter.

After the sticker shock of getting estimates from professionals, I decided to get this and do it myself. After a month with two dogs I can report the system is working flawlessly. It works just fine and I saved 1300 bucks even with the extra cost of buying an edger trencher. I do have some tips for other do-it-yourselfers. Digging the trench is a pain. After some trial and error I bought a WORX WGB96 12 Amp 7.5 inch Electric Lawn Edger and Trencher. Got it on for around 80 bucks. The serrated teeth chewed through 600 feet of my yard. The other pain is getting on your knees and trying to get that 20 guage wire in the narrow trench. I ended up using a 3 foot brake line from the auto store and stuck the wire through it and just walked along the trench with one end stuck in the ground. 100 times faster than jamming the wire in with a paint stick. Overall, I'm quite pleased with the system. Wasn't hard to set up and the instructions were easy to understand. Took my dogs 2 days to learn and won't leave the yard even with all the squirrels teasing them. I'm happy....
