I liked this training collar as our terrier seems to go deaf ! This as been very helpful

Perfectly. a vibration and sound. For dog size need to take in. Very satisfied, recommend! Really helps. Collar is working properly. Everyone is happy.

Goid and does the trick for the dog

The set appears to me to be very good quality and the collars could be adjusted to fit …

It actually works!

Very boisterous 8 month old Lab puppy with some unacceptable but hard to break habits. I debated for quite a while about buying this collar due to the price. It's been worth every penny. 5 days after first wearing it and the Labrador is much calmer. Her most frequent bad behaviour (playful attacking an older dog when going into the garden) ceased within a day. Less repetitive bad habits are taking longer to break, but the puppy is calmer and definitely more responsive. Everyone is happier. Just wish I'd bought it sooner!!...
