Works great as a training tool .

I got this for my chihuahua, he would bark and cry when I left for work, and my son would complain all the time.. it was annoying me to come home to complaints every day... I used it for 3 wks, it worked great.. I only have to use it from time to time if I know I'm working a double or will be gone longer than usual...it's not harmful, either.

This collar works great! I was using a 8 year old petsafe collar before and needed to replace it. This works even better I think, it's really handy not messing with battery replacements and it charges fast.

So far it’s worked well without hurting our puppy. Happy with this product. The only thing I wasn’t a fan of was the number system it’s a little confusing to figure out what the strength level is up or down.

I ordered one of these for my 50 lb pit bull who barks all the time whether it's at the children next door or a leaf blowing by. The beep setting works for him and our yard is finally silent! My other little dog is also a barker, just not as bad, but we decided we needed to buy one for her too. She is an 18 lb Pomeranian mix and the collar fits them both perfectly. So far I haven't had to use to shock feature and I hope to stay that way.

I actually really like this collar as I bought 3 this one for the smallest of 3 dogs. However the largest of the three dogs only pays attention to this collar turned all the way up and just ignores the other two collars completely. This collar works on all 3 dogs but adjust the shock level appropriately.
