My loss is your gain. I bought this unit in 2/2024 but ended up not using much as I keep 17 inch laptop. Great responsive chrome tablet.
Includes pen and pen case came with the unit which I haven't used.
I lost C charger so including ASUS charger which works fine with this unit.
This is 8GB unit which currently sells for $429.
