Review on 🐶 Rechargeable Waterproof Dog Training Collar - PATPET, Suitable for Medium to Large Dogs (8-110 lbs), includes 2 Packs by Karen Mabey

I've only been using them for 3 hours and I've already noticed a big difference in behavior. I only used the vibration setting. I have a Chi/Jack that doesn't listen to outside calls. One click and he comes when called. We walked in and he rushed over to someone who was eating and a reminder/buzz made him turn around. My other Chi/Mix is having trouble barking/growling/whining. I had to quietly snap at him several times with the team. He kept whining, and a soft command was enough to stop him. He barked, growled/whined at EVERYTHING. To the point where I wanted to move it. I do like progress. Update: Unfortunately I had to use a shock for the second dog. It starts up as usual and keeps vibrating, but the impact stops it. Now we can leave our bedroom door open. However, it's nice not to hear a constant, incessant barking or growling. Definitely worth every penny.
