Dear Sir or Madam

I bought an electronic dictionary from your online store on January 1st,but after using it for a short period of time,I found it has some problems.

To begin with,the battery needs recharging after a mere 2 hours of use.This means that I need to carry my charger with me when I go out for a day.In addition,the buttons on the electronic dictionary are so small that it is nearly impossible to type anything with them.Personally,I find this to be completely unacceptable.

Therefore,I would like either to change for another model that works better or a full refund.Your help is greatly appreciated.

                                                                                                                   Yours sincerely,

                                                                                                                   Zhang Wei
