These, physically, amazingly small cards with, nevertheless huge capacity are terrific. My Samsung S4 phone now has now been upgrated to a total 80gb of memory which means I can continue to add programs photos and videos almost ad infinitum.

Bought this last week for a University project. Uploaded around 32Gb of photos through the USB 3.0 connection in around 5 minutes. Decent encryption software and inclusive of a decent length of warranty.

This works in my GoPro very well, very fast. Not sure why this other review give it only 3 stars. I can see the price has gone up since I bought mine in August of 2014. I guess I really got a deal at $49. I wish they were still that price as I need another one.

Happy with the product Received Earlier than expected... The delivery boys well decent and polite Thanks for the beautiful service

I've only had this card for less than a month and it is what I was looking for. I'm using this card for my Samsun S5 phone. I like to keep photos and video that I take on my phone so I could look things up or share with people so I don't delete too many things.

It works well in my mobile phone and in my smart camera. I used about 20 GB in storing my data. There were plenty of space left for me to take photos and videos. I could also review my photos and videos quick from the this disk. I enjoy using it.

SanDisk's Ultra SDXC and microSDXC memory cards make their way through the lab. Follow on as Tyler puts them through their paces to see how they perform.

SanDisk Ultra MicroSDXC UHS-I Card, 64GB, CLASS 10+ SD Adaptor is really a good product and i have lots of happiness to purchage this product. It is chepist and fantastic

Fast

Low Capacity

Used it in my gopro hero3 black for a year. It hasn't filled up yet because it can record video through all three of my batteries at 1080p, 60fps. Very happy.

Great storage capacity; Dependable

It was a little bit of a premium price; being on the leading edge of capacity last year

I bought the fastest Compact Flash memory that I could find for use in my newly purchased Canon 5D Mark III. The Sandisk Extreme PRO does not disappoint with its 150mb write speed (160mb read). It flushes the camera's buffer in mere seconds allowing higher burst mode performance.
