DH and reviewed a few sites and UTube for several dog collars before making a decision. We just got our first hunting puppy in about 10 years. Its been a while! Never used this type of collar with previous dogs. However, we have moved to a densely wooded area and a few commands to our little bundle of joy are NON NEGOTIABLE> So far this is helping him understand that, though he is very very good, easy to train etc. Anyway, our order of the two hunter collars arrived very quickly, two days?? The only thing I will mention is that the clasp on our lanyard was broken. I called and they had that replaced in two days! Very impressed with everything so far. Thank you
