Before buying this product, there must be a lot of friends who think this product is bad for dogs.But I'm here to tell you that the collar will only have a different vibration mode to control every bad activity of the dog.No harm to the dog.Very easy to use, after the dog is very docile and obedient.

Great product in every aspect! We really love that the vibration mode is so adjustable that we very rarely have to deliver a “shock”. We’ve used these collars for 3 weeks and have only had to recharge once. Super impressed by the batter life of the remote and collar. Would recommend this product to anyone that asked!

Excellent product! Meets our needs perfectly.

Works well . Does what it's supposed to. A little bulky .

I like this product and it was reasonably priced

Works great and battery lasts a really long time
