    As advertised 20MB/s to 30MB/s write/read in each of mid-grade Android Huawei phone, Android TF300T tablet, and in Samsung Windows 8 laptop (using microSD-SD adapter). Formated to NTFS using Windows 8 laptop and no problem writing to/from in all aforementioned devices. Only used for < 1 month, can't speak of durability yet.

    I picked up this card for use in a Samsung Galaxy S4 and was thoroughly satisfied with it. Read and write speed were as good as I expected and the card worked well with my new cell phone. I would definitely recommend this card to anyone needing more storage space in their electronic devices that accept this kind of card.

    I was actively looking to upgrade from a 32GB card to 64GB and found a great "Deal of the Day" price that I couldn't pass up. Works perfectly with my phone and easily holds my 3,000+ songs as well as all of my photos. I am also able to quickly transfer files from my computer to my phone.

    I bought this for my Samsung Note 3 not fully understanding all the various microSD card formats. Very happy it works like a champ. SanDisk does it again! I cannot tell a difference in read/write times between this card and my phone's internal memory even viewing HD videos stored on the card. Great card!

    You might as well get the 64gig card! It is only about $10-15 more and has twice the space. Trust me, if you are shooting in 1080p and are going to use anything above 30fps, it will really affect the number of pictures or hours that you can save on the card. Go ahead and get the biggest and best, 64 GIG.

    I got this after Thanksgiving for what I felt was a great deal. I had issues with a Kingston micro sd card I bought online and could not get it to work properly. I decided to pick this one up and it works perfectly. I no longer will buy one of those cheapy cards online and will stick with Sandisk.

    I bought this because I was running low on memory in my 32GB card. This is extremely fast, no lag whatsoever and it allows me to download whatever I need. I have a lot of music and download large music podcasts. This is just what I needed! If your phone allows expandable memory buy this now!

    Wait for this product to come on as a deal of the day, which happens about every other week or so .It has a large storage for lots of pictures, music, files or whatever else you want to store on it. It has been very fast and reliable for me with no issues. Set up less then 10 seconds.

    Black Friday special for a steal of a price, turned my note 3 into a 96 Gb monster! Worth every penny. I just had a baby so I can take more pictures than I know what to do with and play him music for hours on end!

    Reliable and durable, this is a nice, fast, economical SD card. Also the two tone color scheme makes it easier to find on a variety of surfaces (table, book, floor, etc) when dropped... It is a perfect add on for my Mocrosoft Surface to double my storage space.

    A good solid micro SD card, bought for use with a GoPro camera. Haven't yet ran out of space on it, though we do download the videos daily. I think the battery would actually die before filling up the card. Def recommend the larger card for the Go Pro camera.
