Initially I thought you could only train one dog at a time- which is technically true. However, when walking two dogs on a single leash that branches into two, they both can hear the noise. After a few days they simultaneously corrected the pulling behavior. In terms of battery life, I only really have them in these collars for a few hrs a day, so they have not run out. Vibration is adjustable, only used a few times because the beeping a verbal cues have so far been enough. Very easy to switch between the two dogs once I got a hang of it. Highly recommend! ...

I'm glad I ordered these.I have two sausages.One is one year old, the other is 11 years old, deaf.The dog is still learning not to bark at dogs or people while walking. What about the other one?She just likes to bark.I've been using this for 2 days and I like it now.I can beep or vibrate both collars at the same time (it does vibrate, which I will avoid) or turn a collar to correct the dog.It's great logistics fastThere is no error in the object and picture.It looks good on a dog

I have a one year old pitbull mixed who barks at a knock or loud noise. I have tried many things to get his attention when he’s barking but nothing worked. I tried a different brand and he didn’t respond to the sound, vibration or even the shock. I gave up on training colors but recently decided to give it another try. He’s had this on a few times and it really works! The sound is loud enough that he hears it when he stays barking, the vibration is strong and I haven’t had to shock him. This collar has also made walking him on a leash sooo much easierThe battery life has been great so far. I really like that the battery life of the collars and the remote control is displayed on the controller ...

So far so good. It’s nice to get the two collars and the ‘lock’ function on the side of the remote is a good feature. The dog responds to all the options.I will say, the remote is a little big and I wish there was a clip for it. Also, the collars would be better if they were easier to adjust.

So far this product is great! The vibration is strong and so is the shock (my fiancé tried it on himself, not the dog) my dog is very responsive with this collar when needed. And I love how you can use it on multiple collars and switch the training to which collar you want to use. The only thing about this i don’t like is how the collar doesn’t stay where I set it to fit, it slides from where it was set but it’s not something that can’t be fixed.

Great collar for my 4 year old German Shepherd. He got very rebellious for a while running away to neighbors when he got let out. Just the beeping is enough for him to listen. Haven’t used the shock yet, however my 2 year old hit the button once and it appears to work well. The battery life is unbelievable, going on 4 days no charge for the collar and remote. My old collar we would have to charge daily and there was no battery life indicator. The remote tells you the collar and remote battery life. ...
