I use this product with my granddaughter who lives a reasonable distance from me. As she doesn't have a phone, I found this as a solution! We are delighted with it. And I am happy just like my daughter.
+ visible color and can be attached easily
- I don't think it works as it should bad sound
This was disappointing. One absolute characteristic of a whistle in water is that it floats. This doesn't float.
Basic whistle. When it blows, there is a sound.
Has not been used, but compact and handy! I would think I will run my case if necessary.
Works and well
