    • Believe the "Fake Card" Hype - Photo to Prove It
Capacity: 200GB
Review Image by Jeffrey Fahndrich
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! ... show more

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

    • Average write 14MB/S
Capacity: 32GB
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."

Capacity: 32GB

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!
Capacity: 128GB
Review Image by JJCEO
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. ... show more

    • Always check if the card is legit when it arrives
Capacity: 256GB

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. ... show more

Dead on Arrival. I was never able to format it. The worse part was that when I tried to pull it out from my laptop card reader, I burned my fingers touching it! The card was extremely hot. I took it out using a piece of cloth and once it cooled off, I could see that part of the adapter was melted. If I would had leave it plugged in more time it could have easily caused a fire. I have been using memory cards a lot, this is the first time something like this happened to me. ... show more
