The RX-070 Micro Receiver is E-collar Tech's newest receiver designed with the smaller dog in mind.  Approximately 20% smaller and lighter than the RX-090, Its unique design allows the user to turn it 90 degrees on the strap so contact points can be before and aft if necessary for a very small neck.  Contact points are 1" apart from one another rather than the traditional 1.25" span.   

Compatible with all current transmitters including the ET-300, ET-400 and EZ-900 and more.
