Query: If you can't read Chinese, please be warned

Initially I bought this product for myself, so I can learn Mandarin and Cantonese. Please be warned that the instruction is in Chinese. When you first put the battery in, a question in chinese shows up. After the initial set up, it was a easier to use. Since my wife can read chinese, I wrapped it up and gave it to her. If you can have the initial set up done by a person who can read chinese, you should be okay.
