This is one of the best training collars we have used. So good that we ordered a second one so each dog has one and we have recommended it to several other people. It has 3 options, beeping, vibration and shock. Each option has several different settings. The collar comes in many different colors. It is very sturdy and it is waterproof. It is adjustable and the clip is very sturdy. I had previously bought a different training collar that did not phase my dog in the slightest and was a complete waste of money. It always seemed to be low on battery even after charging, this one however lasts like a week after charging. I will continue to use this brand for sure
