I had high hopes for the Oppo Pad Air. But I have faced two big issues since I bought the tablet. The first one is weak performance. Whether it is gaming or multitasking, the tablet performs very slowly and encounters a lot of heating and lagging issues. The second big issue is the battery. Although it has a 7100Mah battery, it does not last that long, and I have to charge the tablet more than once a day. The charging speed is also pretty slow. I would not recommend this tablet to anyone.
