This item is a fake. I've encountered others, but this is the first on Amazon.There are others, so beware. It initially reports the proper storage size, then once written to it usually crashes. You can try to reformat it and it will not work. Stick to name brands.
I bought this to burn an image of my RetroPie so I will have a backup. The original is on a Sandisk 128GB SD. I created an image of the original and even was able to shrink it by about 1GB. I still would not fit on this SD card. the Sandisk card formats to almost 1.5GB larger capacity. None of the 128GB cards actually format to 128GB. This one formats to a little over 117GB. If that is not an issue for you this card might be ok. I will have to send it back as I have no use for it. I should have spent the extra $1 to get the Sandisk.
I've found that sometimes my go=pro says the card is corrupted, and can only be fixed by reformatting. It happens about half the time when I use this card with my gopro taking time-lapse photos or videos. The card still works without reformatting (just cycle off and on the go pro, or remove and reinsert the card), it juts hasn't captured anything new. I haven't had a problem with shorter uses, like 4K slow motion, only when I leave it plugged in and running. The shortest session I've seen this is 30-60 minutes. more often it's when I've left it overnight.

I'm not sure whether the speed will matter for my intended use. I will be using this to store vacation photos (low quality camera), a few maps if Google maps allows use of SD, and any apps that can be transferred to SD. Internal storage is just 16 GB on my phone and seems to be nearly full. It is annoying that apps transferred to SD seem to migrate their way back to internal storage quite regularly - probably with every auto update. Let's see if this continues with my new SD card.
Capacity indicated is 128 GB. Properties shown in Windows is 117 GB. I believe my phone said 118 GB.
All the same I think this is good value for the low price - if this SD card lasts. This is day 1 for my experience with it. It booted up without any issues in my LG Android phone and in my laptop using the adapter provided.
I purchased a two-pack of the 128GB U3 cards for my DJI Mavic 2 Pro with Smart Controller, and neither of them would work in the Smart Controller. Tried re-formatting, etc from my PC. The cards would literally lock the controller up and disallow it from shutting down completely until removed. The cards worked fine in all of my other testing (including h2testw.exe write/verify via USB adapter), but I didn't need them for anything else. Communications with the seller just led to a series of back and forth emails which didn't go anywhere, so I ended up just returning them. I'm not sure who to fault for this incompatibility (SP or DJI), but there is an incompatibility. Too bad.
I bought 2 of these high performing micro sd cards. I used 1 memory card for our Nintendo Switch lite and worked as advertised - zero problems recognizing the card. I used the 2nd memory card for my son’s Nintendo 2DS and would not recognize the memory card. At the moment I don’t know if it’s a Nintendo or a memory card issue.
Great option for storing things like dashcam footage on. I have had issues with my VIOFO A119 stopping recordings mid way through and restarting with a new file when the card gets near full capacity. The files should just be overwritten to make room, but this card seems to have issues with that. A simple format gets it all working again and with this amount of storage it takes about a month and a half to fill it with 1440p 30fps footage. Wouldn't trust it for photos or files you care about though.
This SD card works great EXCEPT the speed is much slower than other cards. It came labeled with Nintendo switch on it, I am using it on my switch but the read times make it really hard to actually use it to play emulators etc. Will be looking for a replacement that’s faster
