SanDisk Mobile Ultra 64GB MicroSDXC Flash Card Model SDSDQUA-064G-A11A SanDisk Mobile Ultra 64GB MicroSDXC Flash Card Model SDSDQUA-064G-A11A

Pros: Extremely fast transfer speeds. Takes my Samsung Galaxy S4 from 16GB to 80GB worth of storage. May never need another phone again... (said everyone 3 years ago, but you know what I mean).

Cons: None

Other Thoughts: Thank you, NewEgg!

Pros: I recently switched from an iPhone 4S to a Droid (Samsung Galaxy SIII) and needed a 64GB microSD card. SanDisk always proved to be the leader in flash drives, so I knew the quality would be there. I have dealt with no-name brands long enough to realize that a good flash drive is an investment and I definitely made the right choice with this.

Cons: No real cons. It's very small and easy to lose but that is with all Micro flash cards.

Other Thoughts: Works as expected. NewEgg shipped it a day early (technically the reseller is, but NE gets the credit in my book).

Pros: Great capacity
Plug and ready to use in my Galaxy Note 2

Cons: Price

Other Thoughts: Job is done

Pros: compatible with my windows phone. Gave it more memory then any Iphone on the market

Cons: None

Pros: I bought this memory because I wanted lots of space and great speed, good enough for FullHD video recording.
I used this memory on a LG phone, which states that it supports a memory MAX of 32GB, but I put this memory in and it was 100% compatible.

Cons: none

Pros: I bought 2 of these items, 1 for my Samsung Galaxy S3, the speed is great and I am able to record perfect photos (lots of them) and Full HD videos. now I have space for my music, photos, videos, movies, etc. You simply can't get anything better than this.

Cons: None, simply none! works great.

Pros: Very good and fast access providing flawlessly in the GoPro Hero3.

Cons: There is a known glitch with the time/day stamp when using a 64 Gb chip in the GpGro's. It is not correct when looking at the files (adjust the internal clock on the camera so that the files are marked correctly).

GoPro acknowledged the problem is with them and not SanDisk

Pros: Great write speeds which allow continuous use in GoPro Hero3 without buffer issues

Cons: none

Pros: -64GB (58.9 "real" gigs)
-somewhat fast (10MB/s writing speeds)
-works fine with a SDHC USB adapter
-works with my HTC EVO 3D

Cons: I bought just one while it was on Black Friday sale

Pros: High Capacity
Fast real-world performance speeds
Comes pre-formatted out the box in exFAT format which avoids the file-size limitation of FAT32 and offers maximum compatibility with most operating systems and devices.

Cons: Poor manufacturing process
Prone to file system corruption requiring reformat
Prone to complete device failure.

Other Thoughts: Several months ago, I wrote a review stating that I rated this was an impeccable product. That sentiment has since changed.

I indeed did purchase two of these. I have found that they are prone to failure and are significantly flawed devices. They also provide no indication of their impending failure until you realize they cannot be written to or the file system becomes corrupt.

I have found that this entire series of cards is subject to failure, especially granted the practically 100% failure rate of these seen by myself and others who own them. This is not a small sample size of 5-10 cards; I, myself, have seen no less than 20 of these fail between myself and my colleagues.

Combined with the sheer volume of reports related to the failure of these devices, I am forced to question the QC process of these cards and would advise people avoid them in favor of smaller capacity cards. I cannot speak to Team's 64 GB card due to lack of knowledge with relation to their performance.
