Alpha waves in your hands?

Hi everybody
found an interesting new device: mechanical alpha waves generator which you could held in your hands and tune the whole body into the relax mode. Do you think it might works?

appreciate your opinion
thank you

It is not clear if it is an electro-mechanical device that acts as a vibration motor or other type. There have been many Schumann frequency generator wrist bands and such. I do know that tactile vibration can be quite relaxing and an aid to 'internalizing' and 'resonating' with entrainment frequencies. Other means like radio frequency pulses are more subject to scrutiny. The waterproof bath aspect seems interesting and requires good engineering.

Thank you!
I know it was designed for the bath, and I tried it personally. In 12 minutes guys helped me to come out from the bathtub, it was so relaxing.

So is it a vibration motor then?
