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

This is a great product for our Dachshund and Corgi. I love that we are able to control the strength of both the vibration and shock. The beeping setting is what we finds ourselves using most. Once they hear the beep they know to stop. Not to mention that the collar is small enough to fit on my smaller dogs necks more comfortably than others we have tried in the past! The only reason I give the controller 4/5 stars is because it takes a little bit of time to switch the controller between the collars. Overall I love this product and would/will recommend to many!
