I have noticed some people complaining about whistling. In the instructions, it makes it clear that you are not really supposed to actively blow out of it. More of a relaxed breath release, which does not create any noise.
Wonderful product & wonderful company!
I wanted to love it but it was too noisy made a whistling sound that was distracting
I use this several times daily to deal with stress and a high heart rate. It's absolutely beautiful and can be worn with anything. I also use this in my busy office because it's silent and doesn't disturb my coworkers. Also doesn't bother my pets.
For my mom who works in a stressful situation

See comments above. Trying to slow breathing in stressful situations. Works perfectly . Also , very beautiful . No one else knows why I wear it . Others just think it is beautiful . It was a great find . I love it !

It's hard to use this for meditation breathing because of the whistling.
My friend and colleague is delighted with this gift!
The perfect reminder to stop, close your eyes, and just breathe....
I absolutely love it. It helps with my anxiety when I'm just sitting it's a reminder and a tool to help me deep breath to calm down
