I ordered this SD card yesterday and got it today the shipping was extremely fast! At first I was unsure of how to install it but it’s pretty self explanatory.. I charged my son’s tablet all day and then turned it off, installed the card, powered it back on and once I unlocked it the tablet pretty much guided me through all of it! I did have to go to the storage setting on my profile and push transfer apps to card but it also told me to do it after it formatted so I didn’t have to figure it out or anything like that! I purchased the 128 GB card for my son’s fire tablet and I’m impressed with how much space he has now! He’s downloaded like 10 apps and he still has tons of space! For what I paid it was definitely worth every penny! If I ever need another I will for sure be purchasing this brand again! Works perfectly for us!

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!

Got these to increase storage for my kid’s kindles. Make sure you watch a quick video for install. Super easy once you know how to format then the cards are fantastic for extra storage!

The device is good so far but installing and setting up the SD card was extremely frustrating. Our Kindle has three profiles, and through trial and error, I figured out that the SD card cannot be set up under a child’s profile. I get why (I guess) but providing that information in a clear, straightforward way seems too logical not to include.

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.

In the past my wife and I had 8" Amazon Fire tablets with 32mb of memory. Recently my wife upgraded both of our tablets to the 10" Fire model with expandable memory. I purchased two 512gb SanDiskUltra memory cards. They were easy to install and formatted quickly. I really appreciate havall of the extra memory as I enjoy downloading books and read at my leisure. No more having to delete books to make space!

Neither Fire TV not Kindle HD8 Fire recognising this memory card. Complete waste of money. Please don't buy..

Bought for extra storage on kids fire tablets, works well once set up. To set up get off of kids profile.

As advertised
