Invisible Fence of Raleigh performs excellent installation and training. I highly recommend them. 1. Do not believe the internet lies that invisible fences somehow "harm" pets. The technology and training protocol result in minimal stress to (you and) your pet. My dog,Teddy the Golden Retriever, is not always the brightess bulb in the bunch, but quickly (by the second breakthrough at each training level) learned his boundaries and the proverbial "safe zone". I was thoroughly impressed. 2. Do not be a cheapskate - purchase the training. All the hardware and technology in the world is useless without a proper training program. The training sessions continue until perfection is reached and there is no additional charge. Many dogs require 3 training sessions, but in my case, a fourth lesson was necessary. By the fourth lessen, Teddy had no breakthroughs (one was recorded in the collar, but it was my wife testing the system LOL). In search of excellence? I found it with this vendor. 3. Technicians/Trainers. I liked my technicians. They were professional, smart, clean-cut and very workman like. Caleb did a superb job training Teddy. Caleb has superb verbal and non-verbal dog training skills. Caleb also has a unique ability to measure the physical and emotional make-up of your pet, and customize the training sessions. Training sessions were completely calm and productive. It is clear to me that Caleb is blessed with a high natural aptitude for training dogs. My installer, Tim, did a high quality installation. He made extra-effort to make sure there were no gaps near the building. For reference, Tim previously served our country in the Navy (Aircraft Carrier). I appreciate his military service and Invisible Fence's commitment to hiring veterans. 4. Cost. I have a 1.25 acre lot. The cost of a conventional fence would have been in excess of $10K and my invisible fence was "dramatically" less. Plus the invisible fence preserves the natural beauty of the lot. FYI - the president of my homeowners association was the first person to recommend an invisible fence. 5. Office Support. I found the office support exceptional too. Upon sending an email inquiry, Danielle called me on Memorial Day. I was not expecting a response on a federal holiday. It's a "wow" factor! I am very pleased with this purchase.
