I have had no problems with the Ultra class of SD cards for many years. The current range are probably the same as the Extreme I and Extreme II of a few years ago. Speeds are fine and the locking switch is much better than on the cheaper brands.

Fast, reliable. Cameras won't need to wait for the card to write to take next shot.

I purchased this memory to use with my new GoPro3 Hero video camera and it performs just fine. The sale price made it a great value. I'll probably upgrade to the 64GB when when the price drops a few more dollars. I'll update the review after a few months if I notice any change in performance.

Easy To Use; Reliable Performance; Writes/Reads fast

This product allowed me to shoot away to my hearts content knowing i had a spare disk to store my photo's should my main disk fill up

Durable; Easy To Use; Improves Product Function; Lightweight

Pulled my 16Gb card to put in my girlfriends phone and put this in my Android. Had to spend some time moving files to the computer and back but no problems there and it is working great on the phone.

Do not, I repeat do not, use the back-up Vault whatever it is called. I followed the 12 page pdf directions & set-up "My Vault" and tried to copy about 12 GB of photos.

Lightweight

Difficult Setup; Poor Interface

Ok - so it's a memory card. lets be honest, there is not a lot that i can say about it that you don't already know. As i was going off on holiday, i didn't want to miss any photos by not having enough memory card space...

Durable; Easy To Use; Improves Product Function; Lightweight

The flash drive has a slow write speed despite the available and fully functioning USB 3.0 port on my neighbors desktopPC. I am currently transferring 20 GB of data, without any increase to the expected 40 mb/s speeds as advertised. Reasons?

I take a lot of digital pictures and also shoot a lot of HD movies and these memory cards are fantastic and the price is unbeatable

I really like the card; it works great with all of my cameras; and it gets used a lot
