Easy to install, very compatible with my fire tablet. The quality is good, as far as price goes it's a good value for the material. The newer tablets are fickle and don't have some of the great logistics like it's older models. So this disk works.

Only two weeks in, but the memory card seems to working great. I got this card for my kindle as it was specifically recommended by Amazon, and my kindle came with only 8 gigabytes of storage, which is ridiculously insufficient for any modern complex operating system expected to accumulate data. Even worse, it's not really 8 full gigabytes. (Also, I got tired of being nagged about running out of space after taking only a few dozen photos.) Computers like numbers that are in powers of 2, and work best with processors and RAM that are built on powers of 2, which is why you usually see numbers like 8, 16, 32, etc. and not "strange" numbers like 10, 21, 43, etc. For this reason computer systems have *traditionally* used 1024 (2^10) as a base when reporting storage usage in kilobytes, megabytes, gigabytes, etc. When it comes to a physical storage medium, however, capacity does not have to be a power of 2; it can be whatever number of storage positions will *physically fit*, the only real requirement being that the computer processor can count that high. Manufacturers are notorious for cutting corners in manufacturing wherever possible then hyping up their products. In the case of the kindle, Amazon used 1000 (10^3) as the base of its "8 gigabyte" claim and aimed for a physical arrangement that would guarantee *at least* 8,000,000,000 bytes of storage (1000*1000*1000*8), over half a billion bytes short of 8,589,934,592 (1024*1024*1024*8). Not surprisingly, SanDisk did the same thing with this less-than-32-gigabyte memory card, as this deceptive practice has become an industry standard. But I digress a bit, my point being that an 8-gigabyte kindle affords you with MUCH less storage space than you would expect, necessitating a memory card for expanded storage, especially since the kindle's operating system uses a LOT of overhead, and every application you install also wants to use a lot of storage. When inserting your new memory card (or removing it) it is best to do so while the device is turned off. Mobile devices are finicky when it comes to "hot swapping" memory cards, often refusing to read the card, or even worse, damaging the card and corrupting data. After you've inserted the card and turned the kindle back on, go to Settings -> Storage, and move all the option sliders to the right to tell your kindle to utilize the memory card as much as it is willing to. Unfortunately, some features will still waste space on the internal storage, e.g. screen captures and blue tooth file transfers will NOT be saved to the memory card. To "move" my kindle books to the memory card, the easiest way was to delete them then re-download them. To move other personal files to the memory card, I connected my kindle to my PC and used Windows Explorer. From the previously mentioned settings menu, you can also move *some* applications to the memory card. Before and after the move, the amount of storage used on each disk is displayed. Moved applications will still use *some* space on the internal storage, and funnily enough, moved applications use more TOTAL storage than when they resided solely on the internal storage. One application I did NOT move was ES File Explorer, as this is a system-critical application (due to the kindle's shortcomings). It should also be noted that the kindle's crappy built-in file browser CANNOT locate the memory card. The files *are* there, but you will NOT find them without a proper file browser like ES File Explorer. Also, some programs (such as the red Notepad) will not be allowed write permissions to the memory card! A few days ago my wife turned on my kindle and it updated itself which took over half an hour, which seemed unusual because when I observe updates they tend to run much faster. Afterward, my kindle stopped recognizing the presence of the memory card. The solution was to turn off the kindle, remove the card, turn the kindle on, then back off, then reinsert the memory card, then turn the kindle back on. The card is working great, and is less than 3% full while my kindle has less than 1.5 gigabytes free. Update 2018-04-23 Last night just before I went to bed, my kindle battery was running low. I was too lazy to go find a charging cable, so I just turned the kindle off. This morning I turned it back on, with only 12% battery power remaining, and found that several program icons were dark. When I tried to launch one of them, I was told that the program couldn't run because the memory card could not be found! I tried removing the memory card and restarted the kindle like I described in my original review, but the memory card could STILL not be found. I took the memory card out and connected it to my desktop computer and confirmed that it was in perfect working order. I then put it back in the kindle and connected the kindle to my computer, letting the charge process turn the kindle on. The darkened icons were still dark, and I saw a flash of the memory card icon at the top-left of the screen. I opened ES File Explorer which located the memory card and showed me its files. I went back to the home screen and none of the icons are dark any more. I guess my piece-of-crap kindle doesn't want to exert any effort accessing the memory card if the battery power is red-lining when the device boots up.

Normally, I've never had difficulty with SanDisk products, especially since I have a microSD in my New Nintendo 3DS XL, but I have been hearing the difficulty some have had with the product when it comes to storing personal videos and photos. For some reason, when you turn the Kindle Fire off (as opposed to just placing it in stand-by mode), then turn it back on, the Amazon Storage SD system will apparently move your downloaded photos and videos into the Others file for some reason. Meaning the files haven't technically been removed as you might suppose (since the SD Storage will still acknowledge the memory is still there), but it does make it become rather inaccessible from the Kindle. Technically when I connect to my computer to locate the files I'm not sure how to find them, or even if i can move them back to the appropriate spot. Overall, the result is usually having you to reformat (aka erase the card), then putting back your personal items on it via backup. Which for me is not really a pain, but having to reinstall apps and restore Amazon Books and Films back on the card can be tedious. So you're probably saying, 'Well, don't turn off the Kindle then.' Consequently, this can be difficult though when you have to do a power reset, like, say you're Yahoo Account is having problems, or you accidentally let your Kindle decharge completely. I'm wondering if the problem does not lie so much with the memory card, since it hasn't actually popped out my files or reshuffled them to Others unless you shut down the tablet completely. But instead possibly something with the Amazon OS which somehow either transfers the files or just makes them inaccessible upon powering up. Overlooking this obstacle, the SanDisk Ultra is a pretty good microSD Card for what it's worth. Hopefully Amazon, or SanDisk themselves, can look into this problem and can rectify it with an upgrade or a way where the card is formatted with the appropriate files you can use to place your photos and videos onto it. As for the book issue, the SD Setting menu claims it will allow books to be saved to the card, however, as with the RiffTrax downloads, the Comixology books will not download to the card for some reason. Perhaps I suspect this is due to the fact these are Third Party services (despite Comixology being part of Amazon) and it defaults to the device storage instead. Still working on it to see if there is a way at least for Comixology books to be saved to the card. I've heard on the lower reviews that they've gotten a PNY 128GB MicroSD, and plan on getting one just to see if the issue is either really with the cards themselves or the Kindle. So far the card storage system works for what it's worth, but like I said, until they can find a way to fix the issue of it shoving the personal files into the Others, I can see this becoming rather annoying fast. My only current suggestion is, to create backup files of your stuff in a separate 'Kindle' file on your computer and just transfer it back onto the card whenever it does this (after erasing it). Hopefully I'll let you know in an update how the other brand works and if it suffers from the same issue. UPDATE: Adding a star because I did solve the Amazon memory issue. Basically I discovered that I was writing folders onto the card through PC. But here's why it went wrong, by doing this the FireOS will not recognize the folders as part of its storage system. In short, when you power down your Kindle, it will automatically dump your personal folders and data into the dreaded OTHERS file. So here's what you have to do to prevent this glitch: Connect your Kindle to the PC (via USB cable/charger). Go to the Kindle icon in the Folders Menu, then into Internal Storage (aka Kindle Hard Drive). Locate the Folders marked Downloads, Movies and Pictures. COPY (don't MOVE) and PASTE these folders into the External Storage (i.e. microSD card). By doing this you will have formatted your card where the FireOS will acknowledge the folders and the contents as part of the Amazon storage. So if your Kindle does accidentally power down, it won't dump your personal stuff into the Others file, making them inaccessible to your Kindle. However, this isn't foolproof but after doing some tests after the above procedure, I so far haven't lost my personal videos and photos on the card. Hope this might help you out.

The card being said from Amazon: was created for the Kindle Fire, but after you buy one, the proof is in the pudding!!!. There is so many options you find for this card after you install your: SanDisk 128 SD Memory Card to your KINDLE Fire. Besides all the options you will have, when you go to check out the card in your "Apps and Games" area after it's in, it has it's own area next to: downloaded app, then you will see "apps that can be movied to the SD Card" that's built right in so you want need a app to move things to your new card. It show you a list of the apps you have on your system that can be moved to SD card, or not. Some apps are not movable, and that's ok! The ones that are not able to move are not supposed to be moved for the reason, they need to read things out side of the card. Some give you options to move anyways, but will tell you that you will not be able to use widgets and other objects, etc, etc. Just don't get a SD App and try to force things in to the card that shouldn't be moved. I find also that my Kindle Fire is faster adding everything to the card, so that's a big plus, even my browser is faster, but we do use Chrome. The reason you hear that 1-to-2% having problems with this card besides coming to the realization after they buy a 128GB card, and see they could have bought a much smaller one since they had plenty of room to begin with. Most also are not waiting for the card to get everything lined up to work correct. Let me explain: Just like you should give time for the Kindle Fire to load correctly, also give your new card time to load, because besides it getting everything ready for you to use it, and carrying a ton of information at 128 GB, it's also checking to see if there are any other apps that need to be moved as it starts up, etc. It's not just a board with apps pinned to it, there is allot of information it is checking on, and also depends on where you added things from, so it can be checking allot of different areas too, thanks to Kindle Fires Åwesomeness!!! You can tell when it's ready, because the Icons on your desktop will turn dark to normal till it's ready to go, so don't be like the 1-to-2%, be smart, be patient!. Did you ever wonder why there are only a few who complain about objects we buy? Well besides they can't spell correctly? There the one who break things screwing around, because if they can't spell, there sure not going to read, and that makes them not patient enough and they think they must complain to get there money back. Being the CEO of "MUST HAVE" Åpps, and Supplies,™ we test ever item for a few weeks inside and out!. We add tons of info, then remove it all, just to add it back in again to see if the card is worthy enough 4Ü! We add all kinds of movies, docs, etc, then check to see how everything came out in the end. The more you use your card, and learn to 're-boot after your last app is installed for that day, the faster your card will be because it's lined up and clean with nothing to stop it. We are just like computers, they need to be rebooted after every download, and so does a Kindle Fire, it needs to be 're-booted after adding anything, and hard-booted if you ever have a problem. If you do not know this, you will be that 1-to-2% with problems because you never took time to read about your KINDLE Fire. That's the first two things you must learn besides cleaning your cache, and making sure you have no malware in your Kindle Fire. These four things are a "MUST" TO KNOW, and that way you can give great reviews too when done :-). Also, the reason we say this is for a: Kindle Fire 5TH Gen 10.1 is we tested this card on one. So those with a 5TH Gen who been looking to find the right 128 GB Micro Card, look no further!. Also, we do not get paid for our reviews, we started "MUST HAVE" for the people that are too busy in a day to wonder what the best is for there system, or the novice who wants what the pro's use. We take on all the testing for you, it's our way of giving back to the world. We have a major following and get hundreds of letters each week asking for reviews, but I tell them this: If we feel it does not make 5 star, and find the item has problems, we then will not leave a review, we will tell you instead what wrong with the product or app, and leave the review for another since we only do 5 Star items, and you know what? Most say: that's all we want, honesty!. There is always better out in the world of course, but this passed with flying colors and works great for me and my team!!! Most want to know what we use on our Kindle Fire's, and as far as Micro SD Cards go, this is it!!!.. Remember always! Life is EZ! For those who SEEK! Especially when it comes to all there "MUST HAVE" Åpps, and Supplies™.. Take it from me (CEO)EZ-SEEK. Don't delay! Buy your card Today! At: Amazon.com THE KING OF KINGS IS COMING!

I got this 128 GIG card to use with my new 2017 Kindle Fire 8 inch Tablet. So far it has worked perfectly with my tablet and it has automatically installed all of my Kindle books, all of my Audible books and many of my apps onto the SD card. Please make sure that your Kindle tablet is properly setup to use the SD card for storage. Those settings are seen by swiping down on the Kindle screen, touching storage and looking at the slide switch settings on the lower part of the screen. Turn all of the slide switches to the ON position which is to the right. I show that setup page in an attached photo. I do want to point out that while this SD card has worked perfectly, not all of your apps will transfer to the SD card. I had about 17 that would not go onto the SD card and they consumed an amazing 12 GB of my device’s internal memory. I simply wound up deleting those apps once I played the game. This is not the fault of the Kindle tablet or the SD card but a problem with the way the application is written. Several of the apps were over 1 GIG in size. This card has worked well and I simply plugged it into my tablet. I told the tablet to erase the SD card to make sure that it was empty and I simply downloaded my items from Amazon. They were automatically installed onto the SD card. I used 50 GIG of SD card memory for 1180 books, 106 large apps and 42 Audible books. I own about 100 SD cards and I always do a speed test to verify the reading and writing speeds before I install the memory. I particularly did this on this card as the web page and the packaging do not list the speeds which is very unusual. The card checked out OK but it is not the fastest SanDisk class 10 card I have ever tested. The fastest write speed on this card was 45.886 MB/Sec and the fastest reading speed was 47.426 MB/Sec. I have attached the graphical test data for your information. I used a USB 3.0 port with a USB 3.0 card reader for the test. I have tested SanDisk Ultra cards that were twice as fast as this one. Overall, this card worked well and I rated it five stars. If I have any future issues I will update my review.
