Discolor for the money is a must buy in the battery last forever. It is great because you can train a dog by just the noise or a vibration and if needed two different shocks. Personally I only try to use the noise and it has been fantastic.

This thing has work wonders my dog was a digger and barker and has stop. I haven’t gone as far as using the shock no more, it just took once.. when I see bad behavior I do the warning sound and if Necessary the vibration but that it is all.

Works great

Battery life is excellent as well as range for the collar.

The shock isn’t harmful so you don’t have to worry about hurting your dogs but it works really well in maintaining discipline. The shock strength is perfect and is super helpful in training. 5 stars

Super easy to setup and use. Worked first time no need to on our dog now she doesn’t run out the door.
