I’ve owned one similar but it was cheaper and broke. This one is rechargeable which is amazing, I use the sound and vibration my dog is very vocal, cries whines and barks. When she sees a dog she nonstop barks even if I try to distract her and give her food so this collar makes her stop that behavior. I don’t even need the collar on 24/7 as long as it’s around her neck she doesn’t bark but when it’s off she’s smart and barks. This definitely works but be careful if your dog is like my dog she’ll make noises to annoy you but trick the collar into not beeping!
