If I'm think right, the memoir pen, is the one thats got a digital read out, of last dose and time/date!!
It was pulled from the market several years ago, due to problems with it recording time/dates dose accuratelly, I did think that they had actually discontinued it..
But with goji says, perhaps they still sale in other countries, as sometimes what available in the USA, Canada etc is here because of licencing reasons, and if they had to licence in Europe they may have decided it didn't justify the cost!!
If it's no longer holds the licence for sale/use in Europe, you might have problems with getting another country (where it is licenced) to supply it... As they would be breaking the law selling it directly to a customer in Europe..
