Could damage your expensive coffee machine

It's surprising that Amazon can sell stuff like this that could damage instead of clean your expensive equipment. I bought these brushes because the design and shape of the handle while odd looking seemed very practical. It's long, curved with a disc-shaped collar that together would help save your hand from hot (potentially scalding) water while cleaning your expresso machine group head at several angles. HOWEVER, the bristles are so stiff and tightly packed with rough flat edges that it might as well be a stiff wire brush or a block of metal or wood. Instead of dislodging coffee grounds from the machine's group head it is likely to push them up into the holes insuring serious clogging with repeated use. It's like shoving or pushing the grounds up into the tiny holes. The more you use it the worst it will be. A clogged machine will require profesional attention or expensive thorough cleaning. Ironically the stiff bristles come "protected" inside a plastic cap. Maybe is to protect the plastic bag from the brushes. Perhaps these might be good to clean a toilet bowl rim or the inside of metal drain pipes. My first reaction was to throw them in the garbage and make sure to avoid products from this maker and vendor. But ill send them back so that maybe Amazon will realize how bad it is.
