This is well worth the money. It helped me train my dog in the field and at home over all. It took my dog from not wanting to bring back the birds just wanted to eat them to where she now brings them to my feet. Also has some good range. Took my dog out with me to put up stands and she took off on a trail of some sort. I hit the bell and she came running to me. On the way out I found what she was going after and it was over 250 yards from where I was. Don't hesitate, buy it - you won't be disappointed
