If you take lots of pictures and videos with your phone the this is the card for you. It leaves plenty of space for memories.

so far it gives longer memory for my phone wish they would have told me about this when I bough my phone but it's all good

I love it. It holds all my games for my tablet and doesn't cause me to lose a lot of space storing them on the tablet.

I've used all kinds of microSD cards for my various mobile devices, with varying degrees of usability. This Samsung microSD is the best I've used. Load times up and down are fast...it simply just works without delay. I'm definitely buying more!

I usually feel more comfortable using products that are not generic. Like most you have to pay more for better specs. I would say it's about average as far as speed and it was on sale so a pretty good deal. The pro version has better specs but costs twice as much. But as with most high tech items now we tend to get caught up in the high performance specs and forget that our actual equipment and usage doesn't take advantage of them anyway. This is more than good enough for my Galaxy S5

Bought 2 when the black friday promo was $25.00 each one for my SAMSUNG NOTE 4 and LG G3 phone. Fast and reliable memory recommend everyone to use...

When I got my new Lenovo tablet I immediately bought this chip to put in it for music MP3 and MP4. Performs at advertised speeds using 3.0 reader and is a genuine high quality product. No bad sectors. If you own a Galaxy S3, the write and read speeds are limited by the phone's hardware to about 20 MB/s read and 9 MB/s write. Be aware of this if installing on a phone with less than new hardware. Other than the previous limitation, I have not had any issues with the card whatsoever. I highly recommend this product to anyone looking for a 64 GB micro sdxc card.

Real easy to install, upload and download. Amazing how much storage space in this tiny little chip. Great technology from Samsung only getting better.

This was surprisingly faster than i was expecting. Works great and even comes with an SD adapter which is always nice

Decent data transfer rate and plenty of storage. I would recommend this card to anyone needing plenty of storage space.

This is a very fast card, particularly suited to not only transferring files quickly but also running as a phone or tablet card for applications as well. In phones and tablets one of the most important things is not just the transfer speed but also the IOPs that the card can deliver. Many class 10 cards have great transfer speeds but terrible and I mean terrible IOPs, often a 5 year old card easily out performs them in IOPs. This card delivers in both areas, fast class 10 transfer speeds 23mb read, 15mb write but also 482 write IOPs and 1668 read IOPs.

I was skeptic when I purchased this 64GB but, I was able to add my music and pictures from off my laptop. It worked well; I added the micro sd card to my cellphone which gave me more space. Also, an amazing price. It definitely has my vote.

Worked well in my Samsung smart-phone. Don't be fooled by these off-brands that you may find for cheaper online. They don't function as advertised 99% of the time. Spend a little bit more and get a product like this from Best Buy that works.

There isn't much to say except that the card works fine, is pretty roomy and I got it on sale. What's not to like?

Can't believe the price I got this for on Black Friday. Outstanding storage for a smartphone or tablet. Class 10 in a micro is wonderful as well.

its ok with it but their are better ones speed wise, but for the price you cannot go wrong and it does its job.

I got the memory card on sale so for 64gb it's worth it except for the fact that it doesn't let you download everything to the memory card. Only some apps c an get saved to the memory card and it makes you save the others on your phone causing you to lose phone space. The memory card works great though and I haven't had any trouble with it so far so hopefully it continues like this.

Picked this up via Deal of the Day for my Note 3. I now have lots of storage on my phone. Easy to install, painless to use. Can't get any better.

This was a great purchase for my son, I was super irritated with making room on his Samsung tablet and after I installed it, the once or twice a week complaints disappeared. Hopefully I only need to clean his memory once or twice a year.

Mounted the microSD in my Samsung G5, formatted it, connected the phone to my PC, copied music files to a new folder on the card, disconnected and started playing the songs/albums on my phone ... no hickups, no glitches, no problems!
