This is an educational toy for children that allows them to enjoy calculations and English problems. I purchased it at Costco quite a while ago. There is some discoloration due to aging. I have confirmed that it works. The keyboard works without any problems, but the mouse does not respond. It might work again if you replace the batteries, but please understand that I cannot guarantee it. By the way, I didn't find it particularly inconvenient without the mouse. Thank you. *** This is an educational and electronic toy that allows children to seriously study English and math with a desktop computer for kids. It is made very similar to a real computer and runs on three AA batteries. It is an excellent educational toy that won the 2005 Top of the Toy Award from Creative Magazine in the United States. It comes with a realistic keyboard, monitor, and even a mouse, so children who want to imitate adults will be very satisfied! It has 30 different programs built in, so children can naturally learn English, math, and other subjects in a quiz format with fun music and sound effects so they never get bored. The keyboard is arranged to fit children's small hands, and the arrangement of alphabets and numbers is the same as a real keyboard. It is also ideal for building a foundation for learning touch typing. In the quizzes, you will use the keyboard to type in English spellings and numbers. As it is an American import, all the words spoken by the computer and displayed on the monitor are in English. #My First Desktop PC #Learning #Kids Desktop PC #English Pronunciation #English Learning #Spelling #Learning Journey #Educational Toy #Educational Materials #Costco
