I wasn't expecting much when purchasing this product as I have tried some much more expensive collars from the "big name" companies, well I tell you this one actually WORKED on my stubborn Lab/Sheppard mix! He had a jumping up problem that was getting out of control, this collar resolved it in a day! now he sits and waits to be pet like a normal dog :) I use shock for bad/unwanted behavior and vibrate to get his attention when he's not listening. Now I am using it on our Pug mix to control his excessive barking, its taking a little longer but its working.
The product itself isn't as tough as some other products, definitely not for sport training, but its not bad. I'm finding the charge last about two days, so just charge it at night and your good to go,
For the price its been the best purchase for my dogs I have ever made!, we can take them places now and people actually enjoy them as hes not jumping and hurting people anymore!! YAY!
