Bests & Worsts Reviews from Amazon

As an Amazon customer I rely on customers' reviews when shopping for a product. This company bribes customers for a 5 star/satisfactory review by promising them a 1-year free supply of batteries. That may explain the high rating this product is receiving and may not reflect the true value of the fence. This product is no more effective than the PetSafe invisible fence (and possibly other products) while much more expensive than others. I bought 2 dog collars for my 2 Great Pyrenees. One collar had such a faint beep that I could not use it to train my dog. I did not receive the promised number of flags for parameter marking. Battery life is short and the size is not standard so you MUST buy them from the company for twice the price of similar batteries. The collars do not have a switch on/off so the batteries are always used even when the system is not connected to the electricity. Everything else is similar to PetSafe (and possibly other systems) and not unique to this company. The product is effective to keep my dogs within the parameter. I'm highly disappointed by the dishonesty of this company and customers who accepted the bribe.
