Card came in and tested fine in Windows, but did not work in my tablet. I contacted support, and the tool they sent me to use to format it failed to work, so they said request a replacement. Similar issues with the second card, but have tested the card in other tablets on display at Best Buy, and it works no problem. Looks to be a port or software issue on my device.
Other than device issues, the card writes around 20-35 MB/s from what I have tested. Read speeds a bit higher, though I have not seen the 80MB/s advertised, could just be limits of the laptop/bus testing it. Seems like a good product, and is a great price for the space!
Really have to give a shout out to SanDisk support on this. Even though it looked like a device (tablet) error, they helped me look at and diagnose the card and didn't hesitate to give me a ticket/incident number to get the card replaced. Really happy with support, just need to get the tablet repaired/replaced so that I can utilize the card I purchased, but works great with Windows so far on transferring pictures/movies!

Well it worked when I got it 12 days ago, I put it into an Honor 6X and all was well, but yesterday the phone started saying no storage space, I'd look and it would recognize the SD card but say that it had no storage space. I'd take it out, put it back in and all was well... for a few minutes. Today I put it in an adapter and attached it to my computer and windows saw it for a few minutes, I ran the partion wizard mini tool and suspicion confirmed the card is completely corrupted... in under 2 weeks. That's just peachy.

Love the space for the cheap price, however...out of ALL the crap I take videos of, my son's High School graduation video was corrupted and not recoverable. However, me taking a video of some dumb waves on the Gulf Coast works just fine. Go figure, just my luck. I did buy two of these, one for me, and one for my son...Both for the Galaxy S7 Edge... My son hasn't had issues, and other than the most important video ever being corrupted, I haven't had issues either... However, just give that some consideration when buying... do you want to spend more to get a higher quality card? For the most part, probably not. But, I would backup photos and videos often if you're not sending them to the "cloud" like I wasn't...¯\_(ツ)_/¯ ...anyhow, it'll probably work fine for anyone else but me...... (and YES, I did format it before using)

this UHS-I card was the cheaper option in my book over the highly recommended Samsung counterparts. besides the fact that I’ve always been partial on Sandisk (and I literally hate Samsung) I’ve had a mixed bag of reviews about this little guy.
An mSD for my Galaxy Tab: this was meant to be used as an expanding storage for my very fast Galaxy Tab S2 8” which supports up to 128GB (yes yes I said I hate Samsung but I got this one for free) and I tended to fill this guy to the brim with movies for my business drives and long flights. Having said that filling this guy anywhere above 30% slowed down the card significantly.
Update: After talking with Sandisk’s support I formatted the guy and tried to keep the card at or below 75% of capacity which kinda seemed to have helped with the video lags. I honestly couldn’t tell nor I went as far as testing it because the card actually crapped out on me instead. An RMA was issued and while it took forever to get my replacement I did get it. I’ll slowly gonna be testing this guy now.

I would give it zero stars if it was a possibility. Purchased it to expand my Galaxy S7 Edge capability. I moved all of my pictures over and everything went well, then my phone began having issues and storage problems within the next week. I reformatted and remounted the card. Now it shows 1.50mb of 200 gb used. However, when I attempt to move anything over to the external storage, it states 'not enough available space'.
Thoroughly disappointed with this purchase. Unfortunately, this occurred outside of return capability, so I am just out the $70.

Used it for 3 months and it crapped out. I was using it in my Galaxy S7 and then the Galaxy said that it was corrupted. I tried formatting it in the Galaxy no good. Tried formatting it in my computer no good. 3 months, That's all it lasts. Not happy. Still trying to find out what to do about this.
When the replacement came it said nothing about returning the original item so after I received the replacement I threw out the original item. It was clearly broken and no use to me. Later they sent me an email that I had to return the original item. So I paid now for the broken original and the replacement. If they say replacement, that is what it should be. If they wanted the original item back then they should have said exchange. Extremely unhappy. Everyone should hold onto their broken original itmes for a month or two just in case. Deceptive way to get me to pay for the broken original item.

Bought two Sandisk Ultra 32GB for my Moto G 3rd gen cellphones, used as a storage.
Same scenario with both cards: first it started unmounting and remounting itself, then it became unrecognizable.
One card dead after 6 month, second after a year. Same cellphones are working with other cards.
I tested both cards on my Linux laptop and I see I/O errors---definitely problem in sdcards.

This is currently the king of high-capacity microSD cards (as of my writing). I need to emphasize a few things:
- It is not fast. Read speeds hover around 60-70MB/sec with my Transcend USB 3.0 reader. Write speeds hover around 15MB/sec.
- Beware of data loss. It seems some aspects of this memory density are experimental, and I've lost one due to data corruption that made the card unable to be read. I had to request a warranty exchange from the company, which they provided easily, but the data is gone.
- Gets hot with prolonged use. I'd recommend copying in blocks of less than 20GB at a time (especially writing), because ultimately the temperature may have been what killed one of mine. I have 3 of these and the others are doing fine.

It's SanDisk.
Udate 2 on February 4. 2017: This card failed completely. It breaks my heart to say this because I've been so gung-ho about this brand. I've purchased many SanDisk products in the past, including SD, SDXC, microSDXC, etc. cards, as well as thumb drives. Given that my brand-new cell phone doesn't recognize this card any more, but does recognize others leads me to believe it's the card. It's too bad, because I was going to purchase a thumb drive from them, too; however, given my experience and the recent comments about SanDisk's quality issues, I'll have to go elsewhere.
Update Jan 23, 2017: I use this card for my LG L33L cell phone.
Mostly, I use this to store audio files from my voice recorder--as well as videos and photos.
I've never had any issues with storage writing or retrieval speed.
Further, even on my phone camera's highest quality settings, I've barely made a dent in the volume.
I highly, highly recommend this card.
