Believe the "Fake Card" Hype - Photo to Prove It
September 30, 2018
Top card doesn't work / Bottom card works. Bought the top card June 18 2018 for a Nintendo Switch and the games would download to 99% and then suddenly I'd get an error. When these cards went on sale recently I bought a new one just to see if it was the card. I could not BELIEVE how different the fonts were! Check out photo. Also the color of the bad card is off (slightly more purple and less red). Sure enough, I was able to download games to the new card without incident. The real product works great but I just can't justify giving 5 stars when I had this experience. Buyer beware!

Defective card
August 13, 2018
After trying and trying repeatedly to use this microcard as a replacement in my Samsung S7 - hours of frustration, seeking guidance from internet, friends, etc. I gave up, thinking it was just my ineptitude. Tried again several times, it would never work.
Finally, decided to try a different/new card. Sure enough...worked right away! So, by now the 128 GB card ordered May 2, is well past its "return by" date, when I determine it is defective. Now what do I do? Searched on Amazon, but found no instructions for this situation.
Giving it 1 star in hopes this can be rectified. I use SanDisk cards all the time and have never had a problem like this before.
Just found out from SanDisk that this card is a fake - not their product. Guess I am screwed unless Amazon steps up and makes it
good. Need to somehow punish this seller "Lecu Computer" for giving Amazon a bad name and customers a bad product!

Didn't last 3 months. We've never had issues with our SanDisk's in the past but our last 2 we've bought haven't lasted more than a couple of months (one for a phone, this one for a tablet). We purchased these to go into our children's fire tablets for added memory for their movies and not even 3 months later, it's no longer compatible with the tablet or any other devices we've tried it with. We've tried all the online suggestions to reformat, erase, etc and nothing.

I paid for 10% of my SD card to be used up, FOR FREE! Tell me where 50gbs went from opening to placing inside my switch, because apparently they dissipated into thin air.

I was really disappointed that the default setting for this was readable only and no rewrite. This has been a massive problem for me, and changing the settings has been next to Impossible. I wanted a device that was store material and from which I could remove the material easily. This has not been possible. I don't know the reason for this, and frankly I don't want to try to figure this out. This should be something that is easy to do, but it is not. Be very careful when you buy this because you will get a non rewritable chip.

Watch the speed of the cards that you're getting to ensure that they are correct for your application. This card did not work at the speed that I needed and had to be returned. I am a semi-professional photographer and wanted to use this card as a backup card in my camera, it was slow enough that I ended up replacing the card the next day after arrival so that I would be able to do my shoot as planned, lots of bursting.
There are online many speed rating sites that should be looked at to ensure you have a card that is the speed you actually need.

The microSD itself is nice and work well on my GoPro hero 5 in 1080p 120fps or even in 4k 30fps.
So the writing speed is correct. I'm not using my Gopro much so even after few month I didn't had to plug the card to backup, store and format it. The only times I had to edit I've don't it over wifi on my phone.
So today I tried to connect the car on my laptop using the provided adapter and... it doesn't work.
There is literally no way to make it work on my computer which have only a SD card port.
So obviously I can't return it anymore, so I have to but an adapter which basically cost the same price than the Micro SD itself...

I recently ordered a micro SD card to upgrade my 3DS storage however on arrival neither my 3DS or laptop could detect the adapter. I decided to wait a while before I posted a review until I received my Portable Card Reader later this week to just make sure I was a problem with the adapted and not with the whole product. During my wait, I found another card adapter in my house and was able to use that one which both my laptop and 3Ds were able to detect. So, in conclusion, the Micro SD card works great, however, adapted was faulty and did not work.

I got the ones sold directly by amazon, so I assume they aren't fake. But, across multiple devices from my fire to my samsung S7, these cards regularly fail to register in my devices or on my computer. I usually have to remove them a bunch of times to get them to work. I don't have a long history with SD cards so I don't know how common this is but I am pretty sure it isn't supposed to happen across all devices.

I bought the Sandisk Ultra 128GB Micro SDXC UHS-I Card with Adapter to use with my Canon 7D Mark II, as my camera will take Compact Flash and SD cards. Most of my other cards are Compact Flash, but I liked the price on this card for 128GB of storage space. I noticed however that the buffer on my camera wasn’t clearing as quickly when I used this card compared to some 400X Compact Flash cards. This card may read fast, which is great for big downloads to the computer; but it did not perform well in-camera as it seems that the write speed is low. I tried a (non-scientific) test using a panoramic head and recording 3 images at a time (HDR). Initially, I tried this with a 400X Compact Flash card and the buffer cleared after each sequence of 3-shots, which are 24 Mb’s per image. I had my camera set to record each subsequent image in 1.8 second increments. Trying the same test using the Sandisk Ultra 128GB card, the buffer on my camera couldn’t keep up, meaning it wasn’t writing as fast to the card. This may not make a difference to some people, but if you are shooting rapid fire wildlife shots or HD video, it could present a problem for you. I destroyed the packaging so I can’t return the card to Amazon, but I wouldn’t buy this card again.

Despite the advertised speeds, my Mavic Air drone says the card is too slow for 4k video, so I'm having to buy another card because this one does not perform as expected.

This didn’t work for me. I tried using it with my Roku and it doesn’t seem compatible. I’m thinking I need to actually order it through Roku.
So, it may work well for others, but not Roku. I gave it two stars because maybe it works well with other brands.
