You get what you pay for. It works, BUT I have major concern with the kind of metal used in the filter holder. First, the shiny finish disappeared after a few washes. Then, the material that is made of started showing some type of dark corrosion that came off when I tried to wipe it clean. This so to speak, stuff, was dark and had a strange smell. This made me smell the holder at the tip end, and it had a strange smell that I could not figure out what it was. I don't know what kind of metal this holder is made of, but that's enough for me. I will not use this again. I will have to spend the money and get something with a brand name that I can trust. You hear all the time how people have been poisoned over the years by using cheap metal pots. Well, I am not taking any chances.
