Silicone Palm Chest Percussion Cup, Chest Physical Therapy Cup, Percussion Treatment for Mucus, Sputum, and Expectoration Problem

I don't know what these are supposed to be used for, but I was recommended this for my Niche Coffee Grinder. It does look like it's for something medical and I wouldn't have any idea about that, but for a Niche Zero Coffee Grinder to clean out the burrs... this works great!!! It's also made of a strong material that it looks like it's going to last for a very long time! If you have a Niche Zero, get this! If you need to for it's intended purpose, get this! :)

Bought this as a makeshift bellows for a Niche Zero coffee grinder. It works perfectly and decreases the already low retention. Definitely worth the small price. It does get a little unsightly after a bit of use, with coffee particles staining it a light brown. Would love if they came in black to mitigate this, but since I'm using it for a different purpose than advertised I can't complain. If you have a NZ, get one.

No instructions on how to use, product is in Chinese I think! We need to look up a video on how to properly use.

Works great

My toddler ended up with bronchiolitis and Our pediatrician recommended I use the cupping technique with my hands to help break up mucus. I didn’t trust myself to not do it too hard or too soft so I decided to get this tool. It’s perfect. No matter how hard I used it, it wasn’t hurting or coming off too hard given the material and the way it’s shaped. I was able to use this and confidentially to help my toddler break up the mucus. It’s a great tool to have for parents.
