Our dog is no longer with us so we are selling our dog collar. The Educator EZ-900 is a great training tool with 7 levels of vibration, 4 tone levels, MaxStim and InstaStim. It has a range of 1/2 mile which worked great whenever we were out on hikes. Comes with a charger for the collar. The remote uses a micro USB charging cable (not included). Functions perfectly. The collar is 15" in total length.
