received in due time on it but no complaints against the calculator has functioned for a few days and of course the return time being exceeded .... have to go through the after-sales service and there Casio c ' is the horror After many complications I finally return address I must therefore return the calculator and wait ... and during that time my daughter has no current calculator ... I can not redeem another because they will fix me / change calculator ... well next time I would buy at crossroads!
