I purchased this new and used it for about two years. It still works without any problems. ★ All the necessary cables for use are included. ★ I will also include the adapter needed for screen sharing. ★ The handle for inserting the stylus has torn, but it does not affect use. ★ There are no replacement stylus tips. ★ Regarding scratches on the screen: They don't interfere with writing, and are only visible when held up to the light. Thank you for your understanding.
