High quality collar with reflective stitching, Maggie, our 5 month old Dalmatian puppy responded to the beep tone and vibration commands on the first day, finally allowing us to enjoy our dinner. Convenient 0 to 99 static stimulation command adjustment.We have not needed to use this feature for now, so we leave the setting at 0 to prevent accidental operation. Neon test light is a plus.Easy and fast charging of the handheld remote and receiver collars. We now have control of Maggie’s jumping on and biting.Highly recommend for training difficult dogs. Thank you NVK! DOOGIE and BEAV
