Bought the collar to replace another one that didn't last the full eight months, only to have this one only last 2 months. I have used these type of collars for 3 years and never had a problem until now. Checked the packaging and it has all of the right can and collar information because I thought it might be a fraud , but that wasn't the case. I guess the quality isn't like when they came. I will never buy it again for my dog or cat......VERY DISSATISFIED !!! User's recommendation: NOT RECOMMENDED...Does not work as advertised.
