I bought a C grade. There is a small scratch in the corner of the unit and one little scuff on the screen, but it is completely invisible when the screen is on and there are no problems with use. The battery, when diagnosed, is also at 100%. I was happy about this as I want to use it for a long time. Charging with the included cable is also fine. I don't know about the adapter, as I haven't used it. (I use another one at home). The operating system was upgraded to iPadOS17 after purchase. My use of this product is mostly for browsing, so the storage is adequate and the purchase was quite inexpensive. Delivery was also quicker than indicated on the screen at the time of purchase. Thank you very much. I will use it with care.
