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! :)

Works great

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

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.

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.

Ok, this thing is MUCH smaller in real life they what they show in their pictures. The person's hand that they show holding this product must be that of a 6 year old, and while the dimensions they give are correct , the pictures they use are very misleading. I'm kind of disappointed because I have seen these in some of the Asian markets around Atlanta that were almost twice the size for the same price. Next time I see some I'm gonna buy two of them there because the amazon ones just not worth it the price.

Bought this for the niche zero grinder in order to push out the stale coffee grinds left in after a grind. I know this isn’t what it was made for, but it works so incredibly well and fits perfectly! First picture is of the item on the top where the beans go, you just tap the top and it works like a billow! Second pic is all the grinds that came out the first time I used it!

Like others here, I bought this to flush the last remaining grounds out of my Niche Zero coffee grinder to get it closer to actually zero retention. It works perfectly in that function. It is also very easy to wash/rinse from time to time to keep it clean. Great purchase!
