Size, type and price are great!

Nintendo Switch memory works best if you match it exactly, and the SanDisk web site helped me do just that. Other online sales points did not clearly specify what was needed. Other memory may work but cannot match the bus demands in the device. My son is very happy with the performance and speed in this memory card.
