We got this set for the whistle so I can only comment on that. IT WORKS!!! Our one year old puppy has been quite challenging to train. When she is outside and starts barking she will not come in for anything ( calling, treats, toys, etc). If you try to get her she just thinks it's a game to play "keep away". The first time I tried blowing the whistle she instantly stopped and came running in the house! Pure magic! It has worked the same every time! Even our dog trainer was shocked and impressed! I wish I had found this whistle sooner, but SO grateful we have it now! Amazing!
