Rechargeable Remote Control Transmitter for M556-1/M556-2/M556-3 Dog Training Collar

The vibration strength seems to not have a harming effect on my dog but it’s enough for him to stop in his tracks and finally listen to what I’m saying. My dog is a year old and he was off the walls, trying to get him to pay attention to me was a hassle til I invested in this item. The battery life is amazing I usually take it off before bed and put it back on in the morning and I have no trouble with it throughout the day. The remote control also has no issues if you are looking for something to help your dog settle down a bit this is the perfect item! Love love love it!!
