This collar has been insanely helpful with training my 10 month old puppy. He behaves so much better now and I hardly even turn the remote on! I give a verbal warning, if he doesn't stop then a beep or 2, then vibration but it rarely has gotten to that point. He knows what the collar can do and I know he doesnt enjoy wearing it but he is learning quickly. Purchased this a month ago and only had to charge it once!
