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 ! DOOGIE and BEAV
