About a month ago we bought this tool because it started with grounds stuck in the nespresso grinder. We had a bit of an accident in our kitchen. I needed to empty the grounds in our nespresso, and used an old bag of coffee beans. Before I got a chance to clean up, my girlfriend then poured the used grinds in to the nespresso. she and i tried cleaning it out as best we could, used a mini vacuum - picking it out by hand one at time - shaking - pounding - scrapping etc, and still the nespresso says - fill with beans, when its already full, and just makes a weird noise when you try and make espresso or coffee. buying this tool helped me to really give the nespresso a good cleaning. my girlfriend and i would like to thank you so much. this is a good product.
