Terrible product
These batteries have such a short life they are almost useless. I have had many break because they are such poor quality and screwing them in the top cracks off. I’ve had no success in getting any response to my request for replacement. Recently I tried again, and I am stunned by Batteries that run out of juice in a couple of weeks

To the point
Items are worth the money. Have a young dog at home that we are training and this purchase was very beneficial for two reasons:1.) The batteries are affordable for our invisible fence collar.2.) The training clicker is a plus, and very helpful when it comes to dog training. The clicker itself is very loud and of good quality, plus It had a clip to wrap around your wrist.
