I see that this provider only receives As, so I guess I am going to be the exception. We had an invisible fence at our home. We got a new dog, and had to get the lines repaired (after landscaping) and dog training. We had an old system. On the second visit, the trainer came out and recommended that we get the new, lighter, micro collar. I asked how much. He told me $500. I went and got my wife, she asked how much, and the trainer said $500. We said no thanks. A few days later another trainer came out, and also recommended that we upgrade. I asked how much, and she said between $200 and $250. I asked her to double check, she called the main office, and told me it was $199 plus tax. I said sure. I just now called corporate headquarters to query about the price discrepancy. Their agent told me that it was $500 if I upgraded the entire system, collar, panel, and so on. But $199 if I just upgraded the collar The agent suggested that I probably did not understand what the trainer was telling me. I know what I heard. And I know that the trainer did not tell me that there was a lower cost option. So, let this be a notice to all those who wonder about upgrading. Also, we had our first invisible fence when we lived in Minnesota. The training involved three visits, with the trainer spending a fair bit of quality time with the dog (about 30-60 minutes each time). From this service provider, the "training" essentially represented the trainer showing me what I needed to do, which took about 5 minutes. The third visit we got a really professional trainer, who clearly knew her stuff and cared about the training, and spent time with the dog. More what I expected.
