We have had our system for a little less than a year and once before the collar stopped working. Thought maybe it got wet so took the battery out and let it air dry. Worked fine. BUT a couple of says ago the collar quit working again. Tried replacing batteries, tried re synching, tried adjusting the connection points for better contact, tried cleaning and scuffing the contacts but to no avail. So called customer service and they were the BEST! They didn't give me a hassle and are sending a replacement since I am within warranty. I love this containment system, just really wish the collars were more dependable considering my trouble along either the many other reviews. But can't praise enough the customer service. Thank you Petsafe.
So far this has worked great. I was at an advantage, as my rescue dog had been using an underground fence, so she already knew what the beeping meant - B-line back towards the house. The batteries need to be changed ever other month - even WalMart has the batteries. I can see where it might be difficult for people with smaller yards that are not circular shaped. I have 6 acres, so this wasn't a problem for me. Indoor unit can not be placed closed to any large metal objects (e.g., washing machine, refrigerator). Also, large metal objects outside (shed) can limit the range. I have been told that Bull dogs can be stubborn enough to sit and take the charge until it stops (30 seconds), then happily go on their way! :D
