I bought another tablet as a spare for one I used to like. It was convenient because it could use a microSD card. I bought it used somewhere, but I've never opened it since I bought it. ※ Addendum I'm sorry, I just realized the product description was strange. I bought it from a reputable place, so there shouldn't be any operational problems. The capacity is 16GB. However, since it has a microSD slot, I didn't worry about the capacity at all. ※ Addendum 2 A remote control was also included. This is the one I used when reading books. I kept it as a set in case my main device broke. It worked well with the tablet, allowing me to turn pages remotely and open other books without touching the tablet, which was quite convenient. By the way, the remote control is new. Functionality issues... None Storage capacity... 16GB
