I got the card to be used in a dash camera. It’s easy to install, and it holds a lot of footage in the storage capacity.

Great card for the money.

walmart.com

I guess  the real question would be:  why is this so inexpensive?   Oh, you mean because it is for a Nintendo Switch?   OK let's not tell anyone that it works just great for basic storage.  I wouldn't use this in a top of the line Sony digital camera.  The read/write is too slow.  But it is just fine for storing epubs, email, memes, some photos etc on a tablet or a phone.

Too good of a deal.

I grabbed the onn 128 GB microSDXC U3 card primarily because of the price, but I want to be clear - just because the packaging says Nintendo Switch doesn't mean that's all this card is good for. I'm using mine in my DJI Osmo Pocket 3 and it has been handling 4K video recording without a single dropped frame or write error.

The U3 rating is the key thing to pay attention to here. That means it meets the sustained write speed requirements for high-definition video recording, which is exactly what you need for action cameras, drones, and yes, your Switch too. 128 GB gives me enough runway for long shooting sessions before I have to offload footage, which I really appreciate when I'm out and don't have my laptop nearby.

Installation was as simple as it gets - slide it in, format it in your device, and you're recording. The card also comes with a full-size SD adapter in the case, which makes transferring files to a laptop quick and easy without needing a separate card reader dongle.

For the price point Walmart has this at, it's genuinely hard to justify spending two or three times more on a name brand card for everyday use. If you need a reliable, high-speed microSD card for gaming, video recording, or just extra storage on any compatible device, this onn card punches well above its price tag. Highly recommended.

Don't Sleep on This Card

I bought the onn 128GB microSDXC U3 Memory Card for $15 and used it in my Steam Deck. It works really well for the price. The card was easy to set up and the Steam Deck picked it up without any problems.

Game downloads and load times are decent. It's not the fastest card out there, but it's fast enough that I don't really notice any difference in my games. I've installed multiple games on it and they run smoothly.

So far, it's been really good and i can't speak about long-term durability just yet.

It's just a good bang for buck overall if you need extra storage for your Switch, Steam deck, or any handheld that supports microSD cards

Very good, buy it already

Since the prices of cards are insanity now. I opted for this one for my epub books for smaller devices since I don't need much storage for now and I can upgrade later once the ai bubble bursts. I won't know about game storage but it didn't take long for my few gb of my library to load onto this.

Still affordable

Works well in the DVR for a 1080p action camera. No problems with it so far. Quite affordable compared to other U3 cards. I foresee the red color being easier to find if dropped.

Works for action cam

So glad I read the reviews.  These cards can be used for other devices also.  I would not go with high speed video quality but below that for security cameras works perfectly.  I am glad I went this route.

Can be used for security cameras with no issue

Short on formatted capacity but otherwise works as expected. Why the store couldn't unlock the display case and remove the product from the large plastic container I had to pry open once I received it I fail to understand. But the module itself is fine. Over priced but does the job.

Formatted capacity is 120 not 128

I bought this for my new security cameras since they utilize utilize micro storage %26 I didn't want to pay for cloud storage right away.  After looking around I came across these and they're about half the price as other options.  These work flawlessly in my cameras.  I'd highly recommend these microSD cards if you're in the market for some.

Great, inexpensive storage option

I bought this as a companion storage device to the Boykeep K30 surveillance camera I bought.  I was unable to sync either to my Jitterbug phone, so returned both.

Unfair Rating
