Excellent. Both my dogs react to the whistle, run even from a long distance. The sound is not very loud on hearing, apparently it works in the ultrasonic range.

The dog reacts strongly to the whistle, but it is necessary to train the animal, because otherwise it will ignore it.

The product is as described. The quality is very good, the whistle is small and portable.

I don't know how it works, but my dog seems to care about whistling.

The product description was accurate. The whistle looks ok.

The dog didn’t care about it, but maybe it's just my dog

The dog responds to the whistle perfectly.

Whistles perfectly and in size very small

Don’t really like the size of it, but it works

Cute, you can wear as a keychain

Very nice whistles, not super loud.

Excellent. I order the second time.

It's small but it performs its function.

The dog reacts to the whistle.

Elegant thing, it works.

100% worked with my dog
