Great Deal, fraction of the price

Very comparable specs to the Lexar 512gb Express Card, but for a much better price. Write speeds are slightly slower (100 mb/s) but the reading speed is the same. I was happy to see this available at my local Walmart!

Lowest Price for an SD Express card I have seen. Came same day which was amazing. Onn is a Walmart in-house brand so I'm sure any problems will be resolved if they come up.

I cancelled my Nintendo ********* order ($59) and purchased this ********* card for only $6 more. Great deal on a difficult to find micro sd express card.
