Review on Enhanced Border Patrol GPS System and Remote Trainer for Dogs - Sleek Black Finish by Marie Jensen

In general the collar works. I stopped using the GPS containment system as the containment circle tended to float too much causing too many problems to trust. My biggest concern is the longevity of the antennas. I had to replace the antennas on both the collar and the transmitter. The transmitting antenna is very long and breaks easily. The antenna collar wire is broken where the collar touches the receiver. The swim collar is also frayed at the adjustment holes, making it a bit difficult to get it right. Customer service is a pleasure to work with, but the antennas are only guaranteed for 30 days. I wouldn't recommend it to anyone because of the price and durability.
