I ordered this for use with the 8" HD Fire I bought on Cyber Monday, and it's working well so far

128GB card is working great in my RCA Galileo Pro 2-in-1 tablet

Its working to expand memory for my Amazon 7 inch the best.

The card is working great, and is less than 3% full while my kindle has less than 1.5 gigabytes free

I took the memory card out and connected it to my desktop computer and confirmed that it was in perfect working order.

Seems to be working as of usage and this review (April 2018)

It's a great deal for the price and for all the storage that it provides on the Fire

But it can on time and as advertised - good deal - now I need another

I think for the money it's great deal all the way around.

Write speed via testing is 45mb/s, exceeds the U1 specs of 10mb/s, can even be categorized as U3 at this rate

You paid for a quality, genuine, fast card, why should you accept the fake?

So far, i'm going to be getting another of these the minute i ordered my upcoming Fire 10 tablet knowing this is one good quality micro SD card

I'd recommend Sandisk to anyone needing quality reliable and fairly fast flash-drive

I find the build quality to be excellent and overall just a good card

Terrible quality.

It was easy to install and worked as expected and supplied the extra space needed.

No problems, worked as expected

Fit my Kindle Fire 8in perfectly and works as expected.

Did the job as advertised, great little card I have a lot more room on my fire tablet for more downloads

Came quickly, works as advertised, just right for holding my library on my new Fire HD8, I put over 2000 books on it and only used 1/6th of the space.

Purchased this for my daughters kindle, easy to get use really fast shipping and now she is happy to have more storage

Well packed fast shipping no complaints

For a week it was great--it let me move a lot of games and apps onto the card to free up space

Thank goodness for these babies, it gives me so much more space for movies on their tablets

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

but it absorbs enough to free up disk space on the Fire

Saves hard drive space; gives tablet more memory

I purchased this to add memory for my Kindle HD 8 because the internal memory is lacking.

I'm sure this extra memory would be good for pictures or videos but does not work for games

Thankfully it was only 20 something dollars because this is easily the worst memory stick I've ever purchased and NOT what I expected from a SanDisk product

The SanDisk Ultra is a great memory card for Amazon Fire tablet

But as mentioned, it is a great memory addition to any Fire Tablet.

SD card worked good to upgrade memory in my daughters amazon tablet.

I've had a different (honestly much slower/cheaper) card in my phone now for

I would and do recommend this SD card for anyone in the same situation.

I DO APPOLOGIZE TO THE SELLER but the card is not reliable

the sd card would have been nice if the tablet had the option of transferring all data at

Perfect data storage option for my tablet for a great price.

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

It became more frequent, but luckily I did not have any issues with corrupted data, so the major issue was having to reseat the card constantly

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

The device is unable to recognize that it has a card in it any longer

The devices either froze or gave up entirely.

The next day when I gave him his Fire to play none of his apps worked and it showed "checking SD for errors" - but after waiting a long time it continued with that message I took out the SD card and checked it in another device - CORRUPT

Used to add extra storage to several portable devices.
