Despite the assurances provided by the really helpful and friendly staff of OSMIO the ordered filters have not yet reached my address in the Rep. of Ireland after almost a month delay or more. This has created unrest and brought us in an uncomfortable position. Initially, I was assured that the filters will be at home last Friday 21/4. A new email received from DHL states that my order will arrive on Wednesday 26/4 whilst unluckily, I'll be out of the country on a business trip. I only hope that a member of my family will be at home to receive it. I am not in position to respond your questions below as the delivery has not been made. I feel sorry and disappointed.
