Community Reviews

This onn microSD Express card is aimed at Switch 2 storage, and the main appeal is that it is a rebranded PNY card sold under Walmart's onn label. The card is reported to work well in Switch 2 setups, with the 512 GB version performing normally for gaming use. The main caution is durability, since multiple cards have failed after about seven months to a little over a year. Promo codes also appear unreliable, so the deal may depend on whether the discount still applies at checkout.

Switch 2 owners wanting a branded Express card for game storage, because it works very well in the console and is described as rebranded hardware from a major flash maker.

Security camera setups needing a microSD card quickly, because it can fill that role and one buyer used it for an urgent camera need.

Reported lifespans range from about 7 months to a little over a year, with one Switch 2 user saying the card lasted about one year. That makes long-term reliability a concern if you need storage you can leave in the console.

The DOUBLE10 and FAST30 codes are reported to fail for this deal, including after adding the filler item and choosing store pickup. One commenter was able to use DOUBLE10 for pickup, but later reports say neither code worked.

The Onn-branded microSD Express card is reported to be a rebranded PNY product, similar to other Walmart Onn flash storage. That suggests the hardware comes from a major manufacturer even though it is sold under the Onn name.

Neither code worked. Luckily I have couple of $10 off $50 from Amex Offer and used that instead. Urgent need one for a card for security cam.
