Nice card

This is an excellent card to use, and has not glitches like some slower cards have in the past.

These "Extreme 64GB SD cards work great with my action camera shooting 4K HD @ 60fps.

Good Solid Card!

Just heard b as co from SanDisk that the card is a fake

I have nothing to say except that SanDisk is a great company that makes great memory cards

This is a great microSD card at a great price

Tried erasing the SD cards and starting over the very next time video files were still bad

I was either sent a counterfeit SanDisk, or a defunct card

tried it on two different computers, neither will recognize any SD card in this thing but work fine with other adapters.

So while initially I was concerned I had inadvertently bought a fake card, with this I was able to validate the speed.

Went on to the sandisk chat, they asked me for the codes on the back of the cards and confirmed the cards are genuine and it’s just a packaging issue

You need a reader cxpable of these speeds or you will think you got a fake card

Great memory card, love it.

Really good memory card works great with the Nintendo switch

Might be the fastest microSD card reader with up to 170Mbs read with SanDisk Extreme Plus microSD card.

This card is crap and should not be used for dashcams

There are plenty of negative reviews of fraudulent cards that quickly fail or otherwise do not have the advertised storage capacity

Good solid card.

The one thing I made sure to note is that the card is shipped and sold by Amazon to reduce the chance of getting a fake card

Nice micro card for my camera

So far its a great card, I will update as I use it over the summer to see if my opinion changes or not

When it does happen, it doesn't even feel like the card is even slightly lose so it obviously is a fault that happens with very little movement

In today's world of rampant computer viruses, how do I know this card is safe to use

The card is definitely defected, and not worth the effort to go through the return process and drop the package off at a UPS store

I highly recommend these cards.

You can not determine the actual memory capacity of a counterfeit memory card by simply viewing the capacity displayed by your computer, phone or camera."So if you think that your card is a fraud and you reside in the United States, then you can contact SanDisk's customer support here: https://kb.sandisk.comI hope that my review is at all helpful to at least a few people and that those who actually do end up receiving good cards but were confused by other reviews gain some clarity, and those who think that their cards are not legit can actually get support from SanDisk.

Based on some other reviews, I was worried these may not be genuine cards, but mine was packaged right and looks 100% real.

With powerful specifications such as A2, V30, and U3, this is the perfect card for action cameras and drones.

This card stopped working the very first time i got out of my camera :(

This cost a few bucks more but it is worth it to have a reliable card that works with no issues.

This card, however, fails at that quite miserably.

Great card at a good price.

First SD card I have had go bad on me, so I will purchase another one and see how it goes.

These are excellent cards and well worth the money

Tried another card (exactly the same card) and it works fine, at least for now

You won't find better or more reliable cards than these Pro SanDisk, and that includes their USB Pro flash drives

People who don’t know which SD card is better or necessary for their Nintendo Switch, I did the research, and for me this is the ideal, enough storage and take advantage of the max speed of data transfer

excellent card with massive storage!card is authentic, verified with sandisk online support and registered the card.

Not necessarily every card that's shipped will be a counterfeit, and I still love Amazon.

card and reader works great.

Genuine Sandisk microSD card.

I love everything, it’s a perfect card for every kind of use.

These cards ARE recommended but the other cards are not

After several tries of getting bad cards, this one fits in my camera, but I have to wait a bit longer to see how it works.

When I inserted in into my smart phone and tried to format it as internal storage, I got a screen that said."This SD card is too slow for use as internal storage.

The cheaper cards would not function in the camera with those settings, these ones work well

Great card so far - is the exact card listed - I wanted a UHS-3 V30 card for my scuba diving camera, and this one was the perfect match.

Card came super fast thank you

After using for more than a month i can say this card is crap, i get slow card errors when it is warm less than 90 out and it freezes my camera

This card is perfect for me

Great card I bought for switch, works well.

I have having issues with my gopro turning off on its own and it was due to the wrong sim card being in it

Love these cards

Lesser cards with all the same speed and transfer speed designations always failed, generated file errors on my drone

Great card and good value.

Although, I am unable to test its capacity level as advertised at this moment, even though I noticed the manufacturing facility to be that of "Malaysia," rather the China, whom are the original manufacturers of the Sandisk/Western Digital Brand, and not the infamous Taiwan Manufacturers of the worthless knock-off, moneygrab, and disappointingly "fake" garbage/gobbage cards they are so well known for.

My Hero6 is getting card read failure

Super fast memory card

and it did not disappoint!!!For the people who are saying that this card is fake because the read or write speed is below what is listed,

Also seems to work great with my GoPro 3 black, I haven't seen a single video record with any pauses or lags slower cards have happen!

Replaced the cards and the camera worked fine again.

sd cards are the best for Android phones, don't cheap out with the less expensive ones.

Outperforms every other card at every price range

I upgraded to this class 10 3 card and recordings were clear and crisp.

I love my SanDisk cards

When it does happen, it doesn't even feel like the card is even slightly lose so it obviously is a fault that happens with very little movement

Also great for video and significantly better than cheaper cards of similar capacity.

Comparing to cheap card readers, this one transfers FAST.

It was a recommended card in a 2017 Wirecutter article that compared the best card

The bottom card is the fake

great performing card for my gopro.

These cards are garbage, 17 mb/sec write and 11 mb/sec read speed

Great cards

The card is now unusable

Good SD card

In fact, If you have read this and are actually still concerned that you have a counterfeit SanDisk memory card then here is what SanDisk says straight off of their website:"All genuine SanDisk memory cards should have a serial number and a manufacturing country's identity

This is an excellent card to use, and has not glitches like some slower cards have in the past.

These cards always work for me

This card is as fast as it indicates.

This is a great UHC Class 3 card that is able to record 4K video with no problems

If they dont have 100’s of good reviews or have a only a handfull they probably are selling fake cards.

I previously took about 20 minutes to burn an SD card for my Jetson Nano 2GB developer kit, using a 32GB card from several years ago

Its amazing that SD cards in general will work great in one device and like crap in another

Its amazing that SD cards in general will work great in one device and like crap in another

Only 3 years, they died (3 cards 16GB Extreme, 1 card 32GB Extreme) with no reason

Just another good MicroSD card from SanDisc.

It’s a great microSd card, and it does the job great

Yeah the SD card is fantastic but why is my name showing up as Turd Fergason

The card writes too slowly to support dashcam use.

Well, Ive been using this sd card for 3 years and its been perfect.

cards are great.

It's possible that I got fake cards or that I just got unlucky and got some lemons, it happens

Other than that, the Card works flawlessly.

I put a similar card by PNY in my girlfriends dashcam and it died in 6 months under similar use

SD Card working well so far, no complaints

There are Youtube videos out there showing things to look for when it comes to fake/cheap SD cards so be advised folks!

so I finally expanded and this card is perfect.

I do not recommend this card for a smartphone.

Turns out, it was just a crappy old card.

If you are looking for a speedy and responsive SD card for your electronic gadgets, well, this is the one for you if your looking to buy Sandisk.

This reader was poorly built, it feels as though the cards will fall out if you shake it enough.

I buy another 2-3 a couple times a year just to always have fresh new cards

Overall, I recommend this card for anyone wanting to record in 4k, as it does what it is supposed to in that regard.

Great card as usual from this company.

Installed in my 4K underwater camera (Paralenz - 64GB limit) to record video without glitches which do occur with their slower Ultra Plus cards.

This is a cheap micro SD Card reader, but it does the job

Like for most cards recently purchased and tested, the card should be formated with full format and test/overwrite of full capacity (not short/fast format; this can easy take few hours).

Great memory card for the osmo action

I have been burned by fake 256Gb cards twice now.

microSD Card Reader - this item gets very hot, and I worry that it will damage my SD cards

SD Card working well so far, no complaints

Before buying these, I compared prices on all of the top performing cards for RPis with overclocked MMCs.

It's not because a card is bad, it's computer math.

Great micro sd card

Great memory card, and the adapter is nice too.

Great card!

It is the fastest SD card I have ever used and perfect for technical applications like boot drives and storage devices for microcontrollers

When I try to format it the card gets corrupted and the only solution is to format it on a pc

This is worse bang for your buck than the 64 gig, but some devices may break if you use an improperly sized card.

Excellent card for my GoPro Hero 5 Black. Plenty of storage.

Best sd card for the money ,thanks .

Card got corrupted on the very first use

I know there are faster SD cards from brands like Samsung and Toshiba etc but for how much more?

Great card for my GOPRO HERO 6

I put this card into my Sony 4K camera and my GoPro — did NOT work.

And it was recognized, and so I simply reinserted the card into the San disk reader and it worked.

The data transfer speed is fast, cheaper than the memory card available on the Go Pro website, and the version is higher.

I love this card for the storage capacity the value for my

I have never received a fake card this way.

Had it happen twice over a few weeks and realized that it was not user error that it was something with the camera - check out support sites to see if this was a know issue - this card from amazon was called out specifically - unfortunately it was too late to return******update- tried multiple steps w GOPRO tech support - do not buy this

Works as it should.

And then it broke in half as I tried to put it back into the raspberry

Worked as I thought it would.
