Super easy setup. There are two settings on the transmitter that you have to play with but once those are tested (it took us about five or six tries) the signal is reliable and consistent.We trained our dog for about a week using the suggestions from the manual and the training flags the set comes with. She’s 70 pounds and has medium length thick fur. We have the strength of the correction on the collar set to 2 which is like static electricity. When we set the strength to 3 it was too strong for her. The battery gets low after about 3-4 months.Our home is set on a slight incline but the radius of the signal still works for us. If we park the car inside the signal radius it does affect the signal occasionally and the collar beeps, she quickly moves away and it stops.We especially like the audible warning signal before administering a correction. Our dog hears the signal and runs back into the safety zone. You can hear the tone of the signal speed up when the collar changes to a correction. This saves our dog from needlessly getting shocked.This product has protected our dog from running in the street, prevented her from going into our neighbors lawns and trained her to stay around our house. She has never escaped. And she does occasionally test the boundaries.The collar activates on a lost signal so we bought a battery backup.Update- after two years the collar stopped working. We called customer service and they sent us a new collar within a week at a discount. Eight months later the same issue happened. The collar does not warn or correct when out of range. This time they sent us a collar for free within 10 days. Customer service is very pleasant and helpful, but I wish the collar would stop breaking!
