Order, shipment, and application of the product was good. I am happy. It does everything I wanted. I highly recommend purchasing the 24 hour electrode adapter. It is far superior than the 2 probes; which in my opinion should be discontinued. My golden retriever doesn't even need the electric stimulation. After 48 hours, he learned when the collar vibrated he needed to heel immediately. I never saw him run so fast. The light on the collar is fantastic! I wish dogtra would offer the light and vibrator only without the electrical input. Additionally, with technical advments, there's no reason dogtra can't reduce the size of this collar. The electronics are ridiculously large.
