The whistle is not bad, but mine needed a little improvement (a couple of turns of the electrical tape on the stem for sealing). I do not know how much it makes a sound in the ultrasonic range, but in the audible range after refining it began to whistle quite strongly. For training dogs most likely instead of it you can absolutely any whistle, but this one is quite simpotichen)). P.S. This whistle is not designed to scare off dogs, do not confuse!!!

Great dog whistle, my 10 month spaniel puppy responds to this very well! I like that you can adjust the pitch of the whistle. The seller was fantastic at getting the item shipped out and delivery was super quick. Very happy, thank you.

I deliver all the goods of good, but I think, shcho van boude is the best and the most rough and far-reaching Chuti-Ogo. For hunting exactly do not play, and so on the decree metriv with dogs and cats can go on

Excellent quality. In the whistle there is an opportunity to adjust the tone of the whistle.

Packed perfectly, fast delivery. The dog reacts to the signal. Let's see during training
