Believe the "Fake Card" Hype - Photo to Prove It

Reviewed in the United States on 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

Reviewed in the United States on 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!

False warranty

Reviewed in the United States on August 5, 2018

Capacity: 64GBVerified Purchase

I had this for my dash cam for about 6 months, worked fine then it suddenly went out, the computer wont even read it anymore...

I emailed about the warranty (10 years) I got told dash cams void the warranty,, I just read the entire warranty and this site as of 8/5/2018 and there is nothing about dash cams voiding warranty...

I wont be buying another one due to the customer support.

Average write 14MB/S

Reviewed in the United States on April 13, 2018

Capacity: 32GBVerified Purchase

Bought two. Both averaged 14MB/s and would burst to about 20MB/s. Nowhere near the 98MB/S claimed. Tried to return same day received (after working with them for 90 minutes, and amazon wouldn't stating "This item note qualified for return."

I got a fake...Beware!

Reviewed in the United States on March 28, 2018

Capacity: 32GBVerified Purchase

I always use SanDisk and think they are top-notch. However, beware of fakes! I got an obvious fake microSD card, and the retail package had obviously been opened before I received it.

Worked perfectly in my testing and in my tablets!

Reviewed in the United States on December 17, 2017

Capacity: 128GBVerified Purchase

I got this 128 GIG card to use with my tablets. So far it has worked perfectly in my testing. I always keep a couple of spares around for my future buys and I seem to give a lot of my SD cards away to family and friends. I picked up this 128 GIG at a great price and I just couldn’t pass it up.

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. This card checked out extremely well. The fastest write speed on this card was 73.143 MB/Sec and the fastest reading speed was 93.368 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.

Overall, this card worked well and I rated it five stars. If I have any future issues I will update my review.

I hope my review and photo of the test data helps you.

Out of 100 plus SD cards I have purchased from Sandisk I have only had one fail. With Sandisk’s 10 year warranty they replaced it and sent me a new one at no charge. That is the advantage when you purchase high tech from a top company that stands behind their product.

I simply called them and returned the old chip and they sent me a new one.

I am amazed at how well these work and how low the price has gotten on a sale day. Putting one of these into your phone or tablet is a wonderful upgrade to the device’s storage capability.

Almost no one needs a 128 GIG chip but at sales prices you can’t pass up getting them.

This is a great product and it makes your smart devices even more powerful.

This is a simple and easy upgrade for your smart devices.

Always check if the card is legit when it arrives

Reviewed in the United States on June 10, 2018

Capacity: 256GBVerified Purchase

Beware of fake cards. The capacity shown on fake cards can be modified to show a size greater than what it actually is. Ex. A fake 256GB card having only 32GB instead. Some unknowing person could use the card without knowing it was fake and find that the data was corrupted when it got past 32GB or encounter a very very slow transfer rate past a certain point.

To check if the card you bought is legit or not use FakeFlashTest (fast) and H2testw (slower but thorough).
This will delete the content on your card so backup whatever you have before using it.

The speed and pictures I got from my legit 256GB card are attached. Your results may vary. The product code is edited out for product support issues.

Reviewed in the United States on April 18, 2018

Capacity: 200GBVerified Purchase

SD card failed after only a couple of weeks, will not read, will not save anything, this was not a good purchase, my previous review was deleted but here it is, in reality I am dissatisfied with the way this was handled, the card was bad, did not work as intended and I wished it was shipped on time. As such I would say stay away, there are other cards and other sellers.
