Would not recover images from a card that was rejected by my computer. Have not had time to fully evaluate.

Multiple attempts to copy data to this card were unsuccessful.  The copy would get to about 16 GB of data, then the card would suddenly show only 1.5 GB of data and folders would disappear.  Tried multiple readers, the SD card adapter that came with it and formatting the card.  Every time resulted in an unsuccessful copy.  Do not buy this card.

Hard to tell, but this may have corrupted a card we where using with it, it was only 'okay' and functioned, but can't tell for sure.

Both wife and I bought these cards for brand new Samsung Galaxy S7 Edge phones.  Both phones appeared to work fine initially, but after a few days my wife was unable to take pictures or access previous pictures stored on the cards.  My phone started displaying the same issues a couple days later, though a reboot would sometimes give me access to 1 picture before all the content on the card rendered as grey boxes in Gallery.  After a week, the card didn't even show up as being mounted.

I WAS able to put the chips into the SD carrier and retrieve (on a PC) the pictures that did get saved, but them reformatted them both and shipped them back to Amazon.

I was using it in Samsung Galaxy S8 for last 11 months. suddenly today it disappeared from the list and status showing as 'corrupted'. fortunately, all my photos and documents are synced with my google and Samsung account. so, I haven't lost any data, but I am bummed. this is my first card failure. contacted Sandisk customer care and they were very quick to respond, apparently, my card had a 10 years limited warranty and as they don't have that particular model, they want to exchange with a 64GB ultra plus model.

Worked fine for 3 days, then became completely corrupted -- unable to read/write data, even unable to be partitioned and reformatted. If you're going to put anything on this card, make sure you have backups in case it dies.

Canon T2i corrupted images and unable to format on PC, Mac OSX or with Card recovery utilities.  SanDisk for this kid.

It seemed to work fine at the beginning using 16gb cards for my canon 5d mark III, on a mac, but then either the computer wouldn't recognize the cardreader all together, or it said that it was empty, when it really was full. Then using a recovery software, I was able to recover all Jpegs, but only few raw files ( I do shoot both jpegs and raw simultaneously ) . BTW, I always format my cards in my camera after the editing is complete.

I hate giving items a bad review, but I did everything I could to get this thing to work.  First off, I wanted this card because of its robust attributes, ie waterproof, shock-proof, etc. I ended up buying 2 of them and they both failed to work.  The problem I was having was that after copying my music and videos to it, they didn't take.  What I mean is, all the files weren't viewable via my PC.  They just weren't there.  When I checked the properties of the card, it showed the total amount of space that was occupied, around 24GB.  But when I double clicked on the card and selected all of the folders to check the properties, it showed only 7GB occupied.  I checked the folders, and there were missing files.  Some folders were just empty.  I tried different laptops, different sd card adapters, a multi-purpose card reader, but same results.  I ended up sending them back and was able to get a refund for both of them.  Thanks to Amazon, it was no biggy.  I ended up purchasing another card by Gskill and it appears to be working flawlessly.

While using the card on my canon T1i Rebel on vacation, the card had a sudden "crash".  I was no longer able to use the card on my camera or view the files on my PC.  Had lost all pictures.

The Disk did not or could not repair my operating system so I am unable to retrieve any of the photos or videos on the computer.

Card worked fine for video in Contour HD and Canon S95 (with SD adapter) for four weeks, then failed completely with "card errors".

I have the 2008 version of this card, and it's started to corrupt some of the pictures we take using our digital camera. After missing some good shots due to this issue, I've totally lost trust in this card and have resorted to buying a new card with better reviews (SanDisk Extreme) in the hopes this issue doesn't happen again.

I'm submitting a warranty claim in hopes of getting a replacement that I can use as a backup card in the future.  Warranty help is online only - there is no support phone number.  I've filled out an online form... I have little faith this warranty claim will go anywhere.

I bought this card from JK Deals and it was dead on arrival and completely corrupted. JK deals has listings all over for these no-name cards. They likely sell them knowing that they are broken, and hoping that people don't bother paying to return them. Do not purchase. Just get a sandisk or samsung for a few bucks more.

I got this card in a bungle with my new camera and started to take pictures with it. As I'm reviewing the photos, I kept seeing "card error" messages over certain images. Not all , but some. I chalked it up to it being a new card and reformatted it. After about the 4th time, I knew it was the card that was bad. I tried different SD cards, SanDisk and Sony, with my camera and they performed without a hiccup. I'm trying to get this card exchanged, but it's quite a hassle dealing with the warranty department. I will not spend good money on Lexar products after this. However, I have their UHS-II card that is working perfectly. But .500 success rate is only good for baseball.
