I highly recommend this company. Not only do they have an outstanding product, but their customer service is world-class. Their sales consultants are very helpful and low-pressure. Work was done on time and within my availability. A great example of thier customer service is their ability to go above and beyond. Example: I recently recommended Invisible Fence to my parents who live in Chicago. Their fence has yet to be installed, but they have their elecronic collar for their dog. They are visiting this weekend and I called Invisible Fence to have them send me the training buzzer which they did (on loan). Now, I can train my parents dog before their fence is installed!-Doug B.
