I purchased this during the COVID-19 pandemic in 2020. It was used indoors, so it's relatively clean. There is some wear and tear (e.g., stretching of the net). The bat and AC adapter were sold separately, but I'm selling them as a set. There are 3 balls. (6 were originally included, but 3 broke - I practiced a lot!) Please purchase more balls as needed. My child has grown up and no longer uses this, so I'm putting it up for sale. Please consider purchasing it.
