For months we had been trying to find some form of 'one cup filter coffee system' suitable for my wife. She had tried the complete systems with coffee and was not impressed, besides which, she has a particular ground coffee that she is very partial to. We trawled vast numbers of shops in the South East of England without success, she tried some which were useless and discounted most as not fit for purpose. In desperation she then started on the internet and finally she found the Swiss Gold One Cup Coffee Filter, which appeared to meet her critical requirements. It was ordered, arrived and was in use within three days and she is thrilled with it. It is sturdy and so will last, it works perfectly and gives my wife just the 'cuppa' that she was looking for. Peace has returned to our household !
