Pros: Small, handy little holder to insert in USB. I use it to put MP3 music on and play in my car's USB port.

Cons: Easy to install backwards x2 because memory chip has no key, and holder has no USB key. Took a couple of tries to get everything plugged in correctly. Once in there, the flash has performed flawlessly.

Pros: Lot's of storage space, good price.

Cons: As with most cards this size, slow transfer speeds

Other Thoughts: Have used a lot of Team products in the past and haven't had an issue.

Pros: Bought this 64g Micro SD card in February of 2014. I use it in my Samsung Galaxy Note 2 for take photos and videos of my kids (1 and 5 year olds). I works great is holds tons.

Cons: It is now July 2014 and the card just died all of the sudden. Lasted a total of 5 months... I took the card out and put in in my laptop but it too couldn't read it. Tried on 3 other devices (Samsung Galaxy Tab 3, Acer Laptop, and my home PC with a card reader), all could not read the card.

Worst part is the loss of all the photos and videos of my kids, which are priceless...

Pros: - Capacity

- Comes with USB adapter

Cons: A lot of electronics don't natively support MicroSDXC because of the format it uses.

Other Thoughts: It is possible to format any SDXC card to FAT32 while maintaining capacity using third party applications.

Pros: It works in my Galaxy S3. I moved all 20 GB of my music onto it and everything checks out.

Cons: Nothing

Pros: Not very expensive for this much of storage, but not cheap either

Cons: For some reason, I can not add anymore data into the gard and it has only like 6G in it. I can not format the drive, I can sometimes read the data in it, but that is about as much as I can do. DO NO BUY it.

Pros: Seemed fairly fast, good price, nice included reader.

Cons: Taking a cue from many others out there, I decided to check this using H2testw and found that it couldn't complete the test - in addition, it was then impossible to format the card - this was tested in multiple PCs, using multiple readers.

Other Thoughts: Returned for a refund, once again Newegg was great to work with, it was just the product that was a problem.

Pros: It's cheap. It works with my Galaxy S4 with no problem.

Cons: None.

Pros: Got this for my nokia lumia 520 windows 8 phone works great, and is just what I needed plenty of space, now my win 8 phone is like my little portable computer.

Cons: none

Other Thoughts: Perfect for storing my music, videos, pictures, and whatever else I need, like software to install on a customers pc when I need to without having to lug a bunch of discs around.

Pros: used a USB 3.0 transcend card reader and benchmark. 45MB/s read and 20MB/s write with smaller data 512kb-64kb peak of 38MB/s write. Great price to performance

Cons: none so far

Other Thoughts: Not the fastest but for the price ahead of the curve. Longevity is going to be the big question!
