Review: Does what it says on the tin - Can't wait for these to go down in price. Bit silly of Nintendo to launch their latest console with the latest in SD cards. Super over pirced because card is new and console is even newer. Still hopefully in time this will become a lot more affordable so I can enjoy my Switch 2 a lot more. Item came as described and works with the Switch 2 as described. Will buy again when on a good deal
Review: Micro SD card. - Good speed compatible with Switch 2 ideal storage capacity.
