Review on πŸŒͺ️ Silicone Palm Chest Percussion Cup for Effective Mucus, Sputum, and Expectoration Therapy by Vijay Patel

Revainrating 5 out of 5

Ideal for Niche Zero coffee grinder

Purchased as an improvised Niche Zero coffee grinder bellows. It works great and reduces the already low retention rate. Definitely worth the cheap price. After some use, it becomes a bit unsightly and the coffee particles turn it light brown. It would be great if they came in black to tone down this but as I use it for a different purpose than advertised I can't complain. If you have NZ, take it.

Pros
  • CONSTRUCTION PRINCIPLE - Special concave lid design, hitting the back with a cup of the palm of your hand creates a drum crushing effect where the air creates a vibration to relieve chest congestion and discharge
Cons
  • There are other interesting options.
