Protonea Senger is an unconventional brand among others in our catalog, as they don't seem to make many coffee products. Instead, they focus on a wide range of commercial fields and applications, and apply their expertise to create products and solutions for professionals and consumers alike. They are a creative group whose professional experience varies from electronics to engineering to marketing - and the Espazzola cleaning tool is a hallmark of that broad specialization. It's a unique approach to a common problem (group heads get dirty quickly, and they're hot and inconvenient to clean by hand), and the product itself is well-made and obvious to use. Best of all, it works super well, so color us impressed!
