I would rather pay this lot around 10 but I must admit that the quality of materials and workmanship are very good. Quality has a price you say ... No taste left by this filter, the infusion is fast and efficient, the cover system that becomes drainer is a good idea, even if it can be improved (cover fashion there is a lot of game, it is a little too big ). Their dimensions are perfect to be used both in a cup of 20cl 60cl in a bowl without problems. I recommend!
