Works great! I read some reviews of the collar triggering randomly inside the house, etc. -- never happened to us! It works well, and our dog learned impressively quickly where the boundaries are.

Exactly as advertised great value

My dogs didn't understand it at first but after a few zaps they learned to where to go and where not to. It works amazingly well. Only put the collars on once in awhile now. They keep inside the lines. Takes sometime to install but well worth it.

Works very good for keeping our 20lbs terrier in the yard and off the street

Great system. Take an entire day for this and you will be fine. Requires you to read all the details and it should work without fail. My dogs both learned quickly.

Works great. We trained a 12year old boston with this and if works flawlessly for almost 2 years
