In my experience, this is the best no bark collar on the market. I have owned hounds since 1978 and have tried them all. Features include:
- Non-electrical stimulation vibration (V) warning before the stimulation
- 7 intensity levels (1-7) for a wide variety of dispositions
- Fits dogs as small as 10 lbs
- 3 LED color for battery indicator Green, Yellow, Red.
- Automatic Level Intensity change based on barking behavior.
- Fully waterproof
- Charger included
