These came on time and as described. They do come in a two pack. They have a number rating so you can have the dog how higher or lower vibration beeping or buzzing. Great for small medium or large dogs. Great to use both for one dog or use one for each of your dogs. Help train dogs they doing less barking and behavioral corrections. Does come with a remote control easy to use. Long battery life. This would make a great gift for any dog lover. Excellent value. We’ve been using these for the last four months and both of our dogs have improved greatly as far as behavior. We were gay neighbor complaints about the Barking at night but the dogs no longer or doing that so our neighbors are now happier and so are we....

It works very well.Like this product, the effect is very good, come back to my dog to use.It feels perfect on the collar, it's a good product, it doesn't hurt the dog, it just makes a sound and a slight vibration on the collar.

We love it
