I bought this item because I have a puppy who keeps going over my fence. I hoped that using this collar would help convince her to stay in her own yard. The first week I had it, she managed to break the plastic clasp on the collar. I bought another collar that is slightly narrower, and therefore i needed to cut a piece of the old collar off and maneuver it into a position to fill the gap so the shocking device will stay on the replacement collar instead of slipping off, as it initially did. Unfortunely, the port for the charger access is underneath the collar. So every time it needs to be charged, I'm fighting with getting the collar back in place after charging (due to the extra strip of fabric I needed to hold it in place). I like the features of the collar - the warning tone, vibration and shock. I rarely need the shock mode, as compliance is reached with either the warning tone or vibration. However, due to the difficulties I've experienced, I cannot wholeheartedly recommend this product.
