Adjustable Remote Control No Bark Dog Training Collar

This Remote Control No Bark Dog Training Collar is, at present, most humane pet training tool. It uses vibration and whistle sound, instead of static simulation, to give your dog No Bark warning and to train pets safely without any hurt. On the controller, it has four buttons to train your dogs.
Features
Uses High/Low vibration instead of static simulation. High frequency vibration is to stop improper action (e.g. barking) of a pet while the low one is to educate.
Sound button. The sound of B-B. You can train the pet to take your orders by different tempos. An insisting training will bring you a wonderful effect. For example, three B-B sounds mean "coming back".
Light button. Press it and the receiver will give flashes of light, allowing you to look for your dog easily at night.
Adjust the length of the collar. The proper tightness should be that you can put a finger in.
150 yard range for useful control.
Without any hurt by vibration & whistle training.
For small to medium dog.
Water resistant collar, but please do not drench receiver in water.
Any warning and user's tips please refer to the Manual.
