Beautiful appearance but absolutely no dog whistles!

These pipes look great and are certainly a must for pipe lovers and for the safety of people, but as a dog whistle utter nonsense. I'll keep still, even though I do not know what to do with the pipes. They are as you know for example. Whistles, only that they do not whistle trilling, but just simply are only arg loud. The chain on the pipe should be removed and replaced with a key ring, because these chains are billigster scrap and keep any day, in other words one would lose his pipe.
Well color and material irritate aluminum and lead to the purchase. My dog ​​will not guarantee set up with this collection even trained on it.
