Very interesting information. Thanks a lot.

I´m not very capable of speaking English fluently by phone, but I´m able to "defend" myself writing. Is it possible to send by this thread or mp the email address? I would like to try it.

Last question, did you send the calculator with the blister parcel that originally came from and the charger, or only the calculator with your own parcel?

Thanks in advance.
