We have a small 12 lb dog and a 125 lb dog. The collar adjusts to both size dogs. I was concerned this product wouldn’t fit the small dog but was very pleasantly surprised, it did. I’m very happy with this product.

This is a great product. I like the simplicity of the remote and how to set the strength of each function. Another addition I like is that the strength can be set to zero and I like this because I mainly use the beeper and the vibration. The battery life feels like forever and connects seamlessly when turned on, off, on, and so forth. The lock feature is handy when it is in your pocket. Since the buttons are front facing it might get pressed in your bag or pocket.

It works just as promised and the battery life is amazing! So far we have been using it for about 3 weeks and the battery indicator has only lost one bar. We only use the beep and vibration mode.

Love this collar so easy to use and recharge is easy.If you have a small dog the collar is not small enough and attachment bulky. Any other dog is great.

This product NVK was perfect, I was a bit leary, so many to chose from etc. It was at an almost complete charge, cuz of course that is the first thing to check get it charging while you read throught the instructions carefully. It work great for my GSD, he was a bit hyper and jumpy when visitors come over, but after 2 times completely differernt dog, I still use as he is not 100% there yet..I do reccommend, and I do use this product, was not paid for the review.

Great product. My dog would non stop cry all the time when he was outside. Non stop it was very frustrating we tried so many different methods. Just with 2 days of wearing it he stopped. We did not have to use it any more days after that. We had it on level 1 and it’s enough just to be uncomfortable but doesn’t hurt.
